What is required in order to have an electric current flow in a circuit?

vhanabebuban — 2022-03-29 06:55:41 UTC

The circuit must be closed in order for current to flow; that is, there must be an unbroken path from the power source, through the circuit, and back to the power source. Voltage, often known as electric potential, is a unit of measurement that is measured in volts. And I Am Vhan abe buban

-I learned that birds are insulators and that's why they aren't electrocuted when sitting on top if wires. I learned that the reason why humans tend to put their hands on their back when working with wires is because they will not be electrocuted. I also learned that coppers are the ones used in wires because they are cheap and a great conductor. Last but not the least, i have learned that electrons flow to the protons and not the opposite in a circut.

The relationship between current, voltage and resistance is expressed by Ohm's Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.

I realised, upon researching the question assigned to my group awhile ago, that I am using a plug without knowing the reason why. I actually thought it was designed to make it look prettier however the discussion made me realise that I thought wrong. Before, the three plug-in pins--- for me, do signifies wealth which is kind of funny. Nonetheless, I realised that 3 plug-in pins are created for something. And it is related to how the current flow within the plug to the socket. And that ground prong was made longer for safety precautions.

Why is the ground prong longer than the other two in a plug?

harveygabrieltinio — 2022-03-29 06:58:28 UTC

It's longer than the other two pins because when you connect the plug in, the earth pin will make contact with the power source before the other two (live and neutral) to ground any unwanted charges in the circuit before the other two pins go inside the terminals. (Harvey Tinio 12-Stem- Altas)

From what I realized is Why Is Ohm's Law Important? Ohm's regulation is fundamentally critical to depicting electric circuits since it relates the voltage to the flow, with the obstruction esteem directing the connection between the two.

Electric current is conducted through a material that opposition to the current (resistance) results in a dissipation of energy, usually in the form heat. This is the most basic and easy to understand effect of electricity on living tissue, current makes it up. If the amount of heat is generated is that can be efficient, and the tissue is may be burnt.

2022-03-29 07:00:36 UTC

Electricity in a circuit can be described by its current,resistance and voltage. Voltage is energy per charge in a circuit. ... Resistance, which is measured in ohms, is the thing that slows current down in a circuit. Ohm's Law is that morevoltage creates more current and more resistance creates lesscurrent.

- The rate at which charge flows is referred to as current.

The tendency of a substance to oppose the flow of charge is known as resistance (current).

As a result, when we discuss these values.

resistance is important, why is Resistance is an important factor in electronic circuits? as it is, higher resistance makes the current flow more difficult, lower resistance makes the current flow less difficult.

I learned about how the electrons are the only thing that moves from one place to another and the positive charges stay on their place. For example when one positive rod touches a neutral metal, the neutral metal will become positive because its electron will transfer or move to the rod, making the rod negative charge. The rod and the metal will then be attracted to each other.

I learned a lot of things with our topic. One interesting thing I learned today is a fact about birds that their feet are rubber, making it a natural insulator of current. That is why birds are not electrocuted when standing on electric wires. I also learned that theres a purpose with three-pin plugs, on why one of it is longer than the others.

Why is the ground prong longer than the other two in a plug?

ivandaveperia — 2022-03-29 07:02:25 UTC

I learned that, when plug is inserted in socket, cause of longer earth pin first it makes contact to the earth hole prior to live and neutral. Thus earth connection is made before the current carrying contacts of the plug become live. When plug is removing from socket, Earth pin comes out last. Means earth connection is removed after the current carrying contacts separate. That earth pin is directly attached on the metallic body of the device, If earth pin is inserted in the live hole, current will flow from the live wire of socket to the earth pin of Iron to the metallic part of the electric device’s body.

alexisangelcuadra — 2022-03-29 07:02:37 UTC

I learned that while the current is being reduced, the resistance improves, considering all other factors kept constant. Objects with low resistance, such as metals, are labeled electrical conductors which allows electricity to flow with ease. On the other hand, materials with high resistance, such as plastics, are labeled as electrical insulators.

- Birds sitting on a wire didn’t get electrocuted since they don't touch the ground (or anything in contact with the ground), so electricity stays in the power line. But, if a bird touches a power line and equipment or other metal that is grounded, it gives electricity a path to the ground, and the bird could be shocked.

zendlerjohnsanandres — 2022-03-29 07:03:33 UTC

I learned why the ground prong is longer than the other two in a plug. It is to ensure our safety. Larger pin of a three-pin plug connects the earth to the body of the equipment and ensures the safety of the person operating the equipment or appliance. When the body of the equipment is properly earthed, the person operating it is protected from the electrical discharge caused due to insulation failures or internal faults.

If indeed the temperature is constant, the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the circuit resistance. Moreover the higher resistance makes the current flow more difficult, lower resistance makes the current flow less difficult.

If the drift velocity is about 0.01cm/s, why do the lights turn on instantaneously when the circuit switch is closed?

mattdanielariz — 2022-03-29 07:03:49 UTC

I have learned in this question is that since the repulsion that causes this repulsion carries an electromagnetic wave, the effect of the closing of the circuit travels down the conductor at roughly the speed of light, and the bulb lights up almost instantaneously

Aaron Cedrick Satingin

aaroncedricksatingin — 2022-03-29 07:06:34 UTC

During our group task earlier, I realized that the 3-pin plug has a different purpose compared to the normal plugs, the 3-pin plug is for the protection and safety while doing its operation. The 3-pin works this way. Since the ground prong is longer than the two pins, it is the one who first connect to the power supply before the live and neutral pin. In that case any unwanted charges in the circuit before the other two pins go inside the terminals.

Hello! I am Jana Rhea F. Latagan and from today's lesson and activity that we've done by group, I've realized that a thing or a person won't get electrocuted even if she's making contact with a wire. Especially if he/ she is only making contact with a wire possessing only 1 electric potential. Because if the person or thing has only made contact in a wire with 1 electric potential, the electrons won't have the motivation to travel up to the one who's making contact with the live wire. He/she will only get electrocuted once they make contact with 2 wires at the same time, containing or possessing different electric potential because by then, electrons will travel that will cause electrocution of the one who's making contact with the wires.

- What I realized about our topic is that it is based on our groupings. When electricians are working on high-voltage circuits, they put their hands behind their backs to decrease the risk of each hand touching things with different electrical potentials and causing a shock, as well as to avoid sending the current into the heart.

Mintalar, Glaiza Marie C.

2022-03-29 07:13:07 UTC

In this topic, I realized that when operating on high-voltage circuits, most electricians prefer to place one hand behind their back so that each hand does not come into contact with things of differing electrical potentials, perhaps causing a shock.

( JEMARK DELA PENA ) electric current, any movement of electric charge carriers, such as subatomic charged particles (e.g., electrons having negative charge, protons having positive charge), ions (atoms that have lost or gained one or more electrons), or holes (electron deficiencies that may be thought of as positive particles)

Realization on the topic "Electric current and resistance"

altheanicolebarruga — 2022-03-29 07:15:29 UTC

I realized that the ammeter and voltmeter measures the difference in electrical pressure each side of the restriction in the water system. There will be a drop in voltage due to the energy used up in driving the current through the light bulb, which has a higher resistance than the wire in the circuit. The overall resistance of an object depends on a number of properties including its length, cross-section and type of material. The longer a conductor, the greater its resistance; for example, a two metre wire has twice the resistance of a one metre wire of similar properties.

If the drift velocity is about 0.01cm/s, why do the lights turn on instantaneously when the circuit switch is closed?

windelbatican — 2022-03-29 07:18:50 UTC

I realized that even though the drift velocity is 0.01cm/s, since there is a repulsion that pushes electrons to move carried by electromagnetic waves. While the free electrons continue moving and immediately begin drifting due to the electric field caused by voltage. An electric field establish instantaneously resulting a net flow of charge at almost speed of light (3×10⁸m/s). So that the lights keep turned on although the circuit switch is closed.
-Windel Batican

Robert Lucas

robertxyzlucas — 2022-03-29 07:23:34 UTC

From what I've learned in this lesson is, the capacity of a substance to impede the flow of electrons is described by resistivity. When electrons hit with atoms, resistance arises. The frequency of crashes depends on the composition, as well as its temperature, density, and length. And also, electric resistance of the material is in Ohms, electronic force in Volts, and electrical throughput in amps.

Physics 2

mikyllakimase — 2022-03-29 07:23:56 UTC

One realization I have learned about the topic "electric current and resistance" regarding with the question earlier "If the drift velocity is about 0.01cm/s, why do the lights turn on instantaneously when the circuit switch is closed?" is that free electrons are already in the wire and electrons do have a slow drift velocity but the electric field caused by the voltage, quickly reaches throughout the whole wire. Therefore, as you turn on the switch the electric field reaches the other end and cause the electrons in the wire near the bulb to flow through your bulb.

The central concept to be noted is, free electrons drifted with an average velocity that is drift velocity at every sections of conductor due to electric field setup by source and hence immediate current flows.

Almodovar, Samantha Abby E.

samanthaabbyalmodovar — 2022-03-29 07:25:35 UTC

When there is too much current, do wires heat up? I discovered, learned from previous lessons and research through , what appears to be happening when electricity passes throughout wires or body tissues. There are really moving electrons, which implies that the higher the current going through the wire, the more collisions between the electrons and the wire's atoms occur. As a result, the wire gets more kinetic energy and its temperature rises as more electrons hit with atoms.

Electric Current and Resistance

margarethnoellecustodio — 2022-03-29 07:35:37 UTC

I realized that, when the resistance rises, the current falls, assuming that all other components remain constant. Electrical conductors are materials that have low resistance to electricity flow, such as metals, and allow electricity to pass through them readily.

MELODY M. DEL SOCORRO

2022-03-29 07:45:38 UTC

In our group activity, while i'm researching, I learned that for the electric current to flow in a circuit, the circuit needs to be closed because, in a closed circuit, electrons flow from the negative to the positive terminal of a cell. or in other words, there must be an unbroken path from a power supply through the circuit then back to the power source.

In this specific topic , I discovered that when working on high-voltage circuits and electric machinery, most electricians prefer to place one hand behind their back so that each hand does not come into contact with objects of varying electrical potentials, potentially resulting in a shock.

Jan Andrei Alcantara

janandreialcantara — 2022-03-29 14:06:43 UTC

One thing that I realized and learned about today's topic, during on our group activity as well that Ohm's law is among the most important in understanding electrical circuits. It is anything that allows electrons to flow in a continuous uniform direction through wires. Wires are not empty as they are already full of electrons. This determines that electron flow occurs in a never-ending loop with no source or destination.

sandaraleilaharellano — 2022-03-29 14:44:41 UTC

The total resistance of an item is determined by a variety of factors, including its length, cross-section, and material type. The higher the resistance of a conductor, the longer it is; for example, a two-metre wire has double the resistance of a one-metre wire with equal qualities. I discovered that electrons are the only things that move from one location to another, whereas positive charges remain stationary. When one positive rod comes into contact with a neutral metal, the neutral metal becomes positive because its electron transfers or moves to the rod, making the rod negative in charge. The rod and the metal will then be drawn together.

Electronic, Reynaldo Dela Cruz

2022-03-30 06:37:05 UTC

I realized in our topic that objects with low resistance, like metals, are named electrical transmitters which permits power to stream easily. Then again, materials with high obstruction, like plastics, are named as electrical protectors. whenever the obstruction rises, the current falls, accepting that any remaining parts stay consistent

Based on the question that is given to us, i have learned that in order to have an electric current flow in one circuit there must be a closed and uninterrupted circuit to its power source

I realized or learned after the activity is, birds' feet are something different like a rubber, which acts as an insulator of current, which is why they do not get electrocuted when standing on electric lines. In a circuit, I also discovered that electrons flow to protons rather than the other way around and also, as I realized, copper is always used in wires as electric conductor.

Lights instantenously turn on when the circuit is closed because the repulsion that causes this push is carried by electromagnetic waves, the effect of the circuit being closed travels down the wire at close to the speed of light, and the bulb lights up almost instantly.

Alicia Mae Pajo

The lesson about Electric Current and Resistance has made me realized the difference in concept between electron flow and conventional current. An electric field occurs when a switch is close resulting for the electrons to flow instead of just randomly moving. Electron flow happens when the movement of electrons is away from negative terminal going towards positive terminal whereas conventional current takes a totally opposite direction. The movement of positive charge particles on the latter part is from positive terminal to negative terminal.

MANAIG AUSTIN JAKE B.

2022-03-30 17:06:48 UTC

Electric current in a wire, where the charge carriers are electrons, is a measure of the quantity of charge passing any point of the wire per unit time. In many contexts the direction of the current in electric circuits is taken as the direction of positve charge flow, the direction opposite to the actual electron drift.

Mendez , Ivern T.

ivernmendez — 2022-04-01 16:28:20 UTC

The connection between current, voltage and obstruction is communicated by Ohm's Law. This expresses that the present streaming in a circuit is straightforwardly relative to the applied voltage and contrarily corresponding to the obstruction of the circuit, gave the temperature stays steady. and generally resistance of an item relies upon various properties including its length, cross-sectional region and the sort of material. The more extended a channel, the more noteworthy its opposition; for instance, a two meter wire has double the obstruction of a one meter wire of comparable properties.

The ammeter and voltmeter, I learned, are measuring the difference in electrical pressure on every half of the water supply limitation. The energy consumed to drive the current through the light bulb, which has a higher resistance than the wire in the circuit, will lead to a significant reduction in voltage.

Electrical circuits are universal in our everyday lives. From the complex coordinated circuits that control the gadget you're perusing this article on to the wiring that permits you to switch a light in your home on and off, as long as you can remember would be drastically unique on the off chance that you weren't encircled by circuits wherever you go.

In any case, a great many people don't actually gain proficiency with the quick and dirty of how circuits work and the genuinely basic conditions - like Ohm's regulation - that make sense of the connections between key ideas like electrical obstruction, voltage and electric flow. Nonetheless, digging somewhat more profound into the physical science of gadgets can give you a lot further knowledge into the center principles supporting most current innovation.

I learned that if there is a long circuit of wire between the power source and a bulb. And even though the drift velocity is 0.01cm/s only, the bulb will light up instantly when you turn on the switch. Because there are already row of electron in the wire that connects the bulb in to the power source and it only need on single push to turn on the bulb instantly.

The body of a bird is a poor conductor of electricity. When a bird comes into contact with a grounded power line, equipment, or other metal, electricity is allowed to flow to the ground, and the bird may be shocked.

2022-04-06 03:10:48 UTC

Repato 12-STEM
According to the recorded session, these are my takeaways.

•If the drift velocity is about 0.01cm/s, why do the lights turn on instantaneously when the circuit switch is closed?
It does take time for the electrons to travel. However, current is just free electrons in a metal travelling in a semi-coordinated manner. The wire is already overflowing with electrons. We didn't need to move electrons from the socket (or some other electron source) into our wire. Electrons have already entered the wire. All you need to do now is give them a little push to get them moving.

-What is required in order to have an electric current flow in a circuit?
three conditions are 1, a conductor in a closed loop. 2, a source of potential in the conductor loop. 3, an electric load to balance the potential in the loop.

-Why is the bird on the wiresafe? When will the bird experience electrocution?
The bird is not an excellent electrical conductor. This means that birds do not allow electricity from the cable to go into their own bodies. Birds can sit on power lines because the electrical current ignores the presence of the bird and continues to flow through the wire rather than through the bird's body. The body of a bird is a poor conductor of electricity. However, While birds on electrical lines are technically safe and aren't in any danger, they won't be so fortunate if they come into contact with the wire and some other objects at the same time. The voltage difference produces a current flow through the bird between the two wires if the second object is an electrical grounding wire or a second wire carrying a different voltage.

Why do electricians work with one hand behind their back?
we don't want the electrical current to enter our body by one hand and then out through the other, because the electricity will flow into our heart, killing you more quickly than if it went into our hand and out through our ground foot.

If there is a long wire circuit between the power source and the bulb, I learnt that. When you turn on the switch, the bulb will light up instantaneously, even though the drift velocity is only 0.01cm/s. Because the wire that links the bulb to the power source already contains a row of electrons, turning on the bulb with a single push is all that is required.

The feathers and skin of a bird are not very good at conducting electricity. When a bird makes contact with a grounded power line, piece of equipment, or another metal object, electricity is allowed to flow to the ground, and the bird runs the risk of receiving an electric shock.
