The live wire in the supply cable carries current from the power station to the electrical device that you want to use. The current returns to the power station through the neutral wire in the supply cable.
For safety reasons, on some electrical equipment there is also a ground wire - also known as an earth wire. It is connected to any metal parts on the outside of the unit, such as a metal case, and to any internal metal chassis, motor framework, etc. The ground wire is necessary to conduct away the current which could otherwise kill someone if a fault or an accident happens which damages the insulation of the live wire so that it touches any of those metal parts and gives them a high voltage. That would be very dangerous to the human users of the equipment.
The wire comes from the installer or manufacturer of the circuit.
Earth wire is meant to protect the user in case there is earth fault in the device or circuit. Only earth wire alone is not sufficient. It needs to be provided with suitable circuit breaker that breaks the circuit automatically.
to assemble a circuit you just need to connect one end of a wire to the battery and the other to the light bulb ( could be another electrical device) now take an other wire and connect on end of it to the other side of the battery and the other to the other side of the light bulb( or an other electrical device. if your circuit is including a switch this is how you do it: ( you will need three wires for this circuit if you have one electrical device) connect one end of the wire to the battery and the other to the switch.Grab another wire and attach one end of it on the other side of the switch and the other to the electrical device (light bulb). Grab another wire and attach one end of it to the other side of battery and the other to the other side of your electrical device. And there you have it how to assemble a circuit
The knot adds extra resistance and inductance to the wire, which in most cases will not make a difference to its performance in a normal circuit operating at dc or power supply frequencies.

A live wire carries electrical current to the device, while a neutral wire completes the circuit by returning the current to the power source.
The live wire carries electrical current to the device, while the neutral wire completes the circuit by providing a path for the current to return to the power source.
The live wire carries the current to the electrical device, while the neutral wire completes the circuit by providing a return path for the current.
An electrical circuit forms a loop. The "live" or hot wire supplies the voltage, which is returned on the neutral. If the hot wire and neutral wire were connected together without a load between them, the circuit would be short out and trip the circuit's protection device.
The common wire in a typical electrical circuit is the neutral wire.
In an electrical circuit, the black wire is typically the hot wire.
In an electrical circuit, the black wire is typically the hot wire.
Yes, the red wire is hot in this electrical circuit.
In an electrical circuit, the black wire is typically designated as the hot wire.
In an electrical circuit, the white wire is typically designated as the neutral wire.
No, the hot wire should not be connected to the ground wire in an electrical circuit.
In an electrical circuit, the white wire is typically used as the neutral wire, not the hot wire.
