In electrical circuits what wire protects the operator?

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.


What are all the parts on a circuit board?

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


Does a knot in a wire affect an electrical 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.


What are three wires that make up an electrical circuit?

In house wiring you have hot (Black), neutral (White) and ground (Bare wire).


What is the voltage source and what is the conductor in a circuit?

The voltage source is the source of the electricity. The conductor is what the electricity flows through to reach its destination. Example: A battery is a voltage source and an electrical wire is the conductor.
