Live wires carry electric current toward a device, such as a main-powered appliance, while neutral wires carry electric current away from the device to close an electric circuit. Live wires are typically blue in color, while neutral wires are usually brown.Continue Reading
An electric current refers to the movement of an electrical charge along a conductor. The amount of electrical flow depends on voltage and resistance, which is mathematically represented by the equation I = V/R, where I denotes electric current, V represents voltage and R indicates resistance.
In electrical appliances, three types of wires are commonly used for safety purposes, which include live, neutral and earth wires. When the appliance is in good working order, earth wires are not necessary. However, faulty live wires require earth wires to discharge a large amount of electric current.Learn more about Electricity
A transformer changes the voltage of an electric current while transferring it from one circuit to another through electromagnetic induction. Fluctuating magnetic fields in the transformer generate an electric current in a coil of wire, and the voltage they put out is directly proportional to the number of turns in the coil of wire.Full Answer >
A light bulb circuit works when the electric current flowing through the light bulb combines with the current flowing in the battery or power source. The filament and wires in the light bulb conduct electricity so that electric current can move through an electric circuit.Full Answer >
The basic steps in wiring a double pole circuit breaker include turning off the electricity, stripping the wires and installing the double pole circuit breaker in the breaker panel. The tools needed for the task include a two-prong light-up electrical tester and a wire cutter or a wire stripper.Full Answer >
A short circuit is caused when two or more uninsulated wires come into contact with each other, which interferes with the electrical path of a circuit. The interference destabilizes normal functioning of electricity flow. The resistance generates a lot of heat in the wires and can lead to a fire.Full Answer >
