Build the indoor wiring to make the electric appliance work.

Home wiring

All electrical devices have a resistance value, and this resistor limits electric current.
A power strip or indoor wiring is a parallel connection of resistors also. The electrical devices in each parallel circuit operated independently.

Due to the nature of the parallel connection, if many electrical appliances are used simultaneously, the total resistance will be small and a strong current will flow.
If it is shorted without passing through resistance, overcurrent flows and there is a risk of fire.

Multimeter

A multimeter is a measuring device that combines various measurement functions such as voltage, current, and resistance.
Multimeters are classified into analog and digital multimeters according to how they operate. Analog multimeters were used a lot in the past, with a moving needle pointing to the scale, but now they are rarely used. Most multimeters currently in use are digital.

Terminals in multimeter

The terminals are where you connect the lead wires for measurement. The lead wire's red color represents the (+) pole, and the black color represents the (-) pole.

1. COM : It means a common ground terminal. Connect the black lead wire.

2. 10A : It is used to measure the current in the range of 0 to 10A. Connect the red lead wire.

3. V*Ω : Used to measure voltage and resistance. Connect the red lead wire.

4. VΩmA : You can measure voltage, resistance, and current in milliamps(mA). Connect the red lead wire.

Resistance measurement

The resistance can be measured by turning the rotary switch to the 'Ω' zone. The resistance value is measured by touching the lead wire to the resistance.

When measuring resistance, pay attention to the range. For example, if you measure a small value resistance in a large range, the measurement result will be '0'. Conversely, infinity (a '1' in the left corner) is displayed when the multimeter's measuring range is exceeded. Therefore, it is better to choose a range slightly larger than the expected resistance value. For example, if you measure a 10Ω resistance, it is appropriate to put the rotary switch range at 200.

Voltage measurement

Since DC voltage (DCV) and AC voltage (ACV) have different measurement mechanisms, it is necessary to turn the rotary switch well.

1. ACV : AC voltage measurement

2. DCV : DC voltage measurement

3. 20 : Measure DC voltage from 0 to 20V

4. V- : DC voltage measurement

5. V~ : AC voltage measurement

DC current measurement

Current is a physical quantity different from voltage and refers to the amount of electric charge flowing through the wire per hour. Therefore, to measure the current, you must cut the wire to be measured. Some devices measure without cutting the wire.

There is one thing to be aware of when measuring current. During the current measurement, the resistance inside the multimeter becomes almost '0'. This is because the multimeter must not interfere with the flow of current. At this time, be careful because measuring the voltage of the battery or the like may cause overcurrent to flow and damage the multimeter. Some high-end multimeters have a protection circuit.

Transistor hFE measurement

The 'hFE' of a transistor is the collector (C) current ratio to the base (B) current. When the base current is '1', it tells how many times the collector current is amplified. hFE is also known as the 'current amplification factor.' When the transistor's three terminals are inserted, a number between about 50 and 200 is output. The output value is slightly different for each transistor.

Continuity test

This is a function to check whether the wires are connected. If the middle of the wire is not cut, a 'beep~' sound is output.

Definition
Electrical circuit: An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances, capacitances). An electrical circuit is a network consisting of a closed loop, giving a return path for the current.

Electric voltage(Regions of a positive or negative charge, such as those at the terminals of a battery) force electrons through a conductor. Electrons that have negative charges can be moved around a circuit.
Originally, the current was thought to flow from positive to negative. This is the so-called 'conventional current.' In reality, the electrons move with a negative charge and towards a positive.

Resistance

Materials have different degrees of impeding the flow of electric current depending on their type and shape. Most materials, except metals, do not conduct current well. On the other hand, metals have low resistance and allow current to flow easily. Pure copper has a very low resistance, so it is mainly used for wire. And materials like superconductors sometimes have completely zero resistance at very low temperatures.

The bulb's filament is made of tungsten, which has some resistance. When an electric current flows, the kinetic energy of electrons accelerated by an electric field is converted into the thermal energy of atoms in the filament.

Incandescence

Iron is initially dark red when heated, but as the temperature increases, it gradually acquires a yellowish color. This phenomenon is because the light's color changes as the material's temperature.

When the light bulb's filament reaches about 2,500 ~ 3,000℃, light in the visible wavelength band is emitted.
All objects absorb and emit light in a wavelength range suitable for their temperature (blackbody radiation). For example, objects at room temperature emit long-wavelength infrared light, allowing you to observe the infrared radiation emitted by people or animals (night vision cameras).
