The name electromotive force is the reason that Voltage is called E in Ohm’s law ( a law stating that electric current is proportional to voltage and inversely proportional to resistance.) . Measuring voltage is helpful with knowing how great the force is, the greater the force, the faster the electrons go. The voltage is very important to a technician, he can tell if a circuit is operating correctly just by reading the volts. ]]> 2016-09-20 00:20:56 UTC https://padlet.com/sme3/4q7jkhrdzjbp/wish/124928902 Voltage  https://padlet.com/sme3/4q7jkhrdzjbp/wish/124928917 Is force that moves/transports electrons along a circuit

In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by both ions and electrons. Where is current used in our everyday lives? Car batteries, Power tools,Copper wires Vacuum cleaners,Many electrical appliances. Current is measured in Amperes or Amps (A) Measuring currentA device called an ammeter is used to measure current. Some types of ammeter have a pointer on a dial, but most have a digital readout. To measure the current flowing through a component in a circuit, you must connect the ammeter in series with it. https://padlet.com/sme3/4q7jkhrdzjbp/wish/124928922 2016-09-20 00:21:02 UTC https://padlet.com/sme3/4q7jkhrdzjbp/wish/124928922 https://padlet.com/sme3/4q7jkhrdzjbp/wish/124928946 Voltage is also called electromotive force

Just like water needs pressure to force it through a hose, electrical current needs some force to make it flow. A volts the measure of electric pressure. Voltage is usually supplied by a battery or a generator.Voltage is the pull of charge from positive to negative.Voltage is a measure of the difference in electrical energy between two parts of a circuit. The bigger the difference in energy, the bigger the voltage.For example, 230V is a bigger voltage than 12V.Voltage is measured using a voltmeter. Some types of voltmeter have a pointer on a dial, but most have a digital readout. To measure the voltage across a component in a circuit, you must connect the voltmeter in parallel with it.You can measure the voltage across a cell or battery. The more cells, the bigger the voltage. https://padlet.com/sme3/4q7jkhrdzjbp/wish/124928955 2016-09-20 00:21:08 UTC https://padlet.com/sme3/4q7jkhrdzjbp/wish/124928955 Current   A current is the flow of electricity. Currents are measured in Amps (A) Current is measured on how much electrical charge flows through a circuit. The more charge that flows, the bigger the current. To measure the current, a device called an ammeter is used. Some types have a pointer on a dial but most have a digital readout. To measure the current flowing through a component in a circuit, you must connect the ammeter in series with it. We use currents every day, from the lightbulbs in our house to charging your devices in a power circuit. Currents are also found in our car batteries to power our cars. Anything that uses electricity, you can almost bet that it has a current of some sort. A current is the flow of neutrons around a circuit. tobbelkl15 https://padlet.com/sme3/4q7jkhrdzjbp/wish/124928975 2016-09-20 00:21:17 UTC https://padlet.com/sme3/4q7jkhrdzjbp/wish/124928975 Circuits Anani  https://padlet.com/sme3/4q7jkhrdzjbp/wish/124928990
  •  A circuit is an electrical grid which is made up of wires which electrons can flow through.  
    •  
          2. A source of power produces the force that give the electrons movement.

          3.When electrons get to a device like a computer of refrigerator the electrons transfer the          
             energy given to them to power a device.

    The current is the flow of electrical charge. It is the flow of electrons moving from the negative end to the positive end. This can determine how much energy can be used.

    It is used in everyday life because it is used in pretty much every electrical appliance, it is how the electrical circuits are able to carry electricity to the light or electric object,
    Current is used in:
    • Car battery
    • Vacuum cleaners
    • Copper wires
    • Power tools
    • And many electrical appliances.

    Voltage makes electricity move through a wire. It is measured in volts. Voltage is also called electric tension or electromotive force (EMF). 
    Voltage is an electric force that causes free electrons to move from one atom to another.

    VOLTAGE FACTS
    It was named after Alessandro Volta.

    Batteries are voltage sources
    Voltage is used in electric power transmission lines used to distribute electricity from power stations to town buildings (houses, work building, schools etc.)

    Can voltage be dangerous?
    Yes. Obviously, the more voltage available to cause electrons to flow, the easier they will flow through any given amount of resistance. Hence, the danger of high voltage: high voltage means potential for large amounts of current through your body, which will injure or kill you.

    The electric charge which flows into your house through your electric circuits carries with it useful energy which you can use for a variety of tasks.

It can also be called electric tension.The bigger or smaller the energy difference the bigger or smaller the voltage is. The scientific symbol for voltage is E because when electricity was only a recent discovery it was called electromotive force. We are now more likely to use V for Volts.

    ]]>     2016-09-20 00:22:03 UTC https://padlet.com/sme3/4q7jkhrdzjbp/wish/124929095     Rachel and Tatiana https://padlet.com/sme3/4q7jkhrdzjbp/wish/124929147 Voltage: an electromotive force or potential difference expressed in volts.
    Define voltage as the amount of potential energy between two points on a circuit. One point has more charge than another. This difference in charge between the two points is called voltage. It is measured in volts, which, technically, is the potential energy difference between two points that will impart one joule of energy per coulomb of charge that passes through it (don’t panic if this makes no sense, all will be explained). The unit “volt” is named after the Italian physicist Alessandro Volta who invented what is considered the first chemical battery. Voltage is represented in equations and schematics by the letter “V”.

    When describing voltage, current, and resistance, a common analogy is a water tank. In this analogy, charge is represented by the water amount, voltage is represented by the water pressure, and current is represented by the water flow. So for this analogy, remember:

    Water = Charge
    Pressure = Voltage
    Flow = Current
    Ohm's law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).

    Voltage can be thought of as the driving force (although it is not really a "force".) behind current.  Things like batteries are voltage sources.  The voltage across the terminals of a battery tends to stay pretty constant.  When you connect a device across the battery terminals a current flows through the device.
    Current flows through electrical elements when a voltage appears across the terminals of the element, just like water flows through a pipe when a pressure difference appears across the pipe. You can use that analogy to get started thinking about voltage.]]>     2016-09-20 00:22:19 UTC https://padlet.com/sme3/4q7jkhrdzjbp/wish/124929147     current https://padlet.com/sme3/4q7jkhrdzjbp/wish/124929200

    A current is a flow of electrons going through a wire and the more electrons flowing through the wire the bigger shock you get.
