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.
In house wiring you have hot (Black), neutral (White) and ground (Bare wire).
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.
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.
The hot wire in an electrical circuit is the wire that carries the current from the power source to the device or appliance.
In an electrical circuit, the black wire is typically considered to be the hot wire.
In an electrical circuit, the white wire is typically considered to be the neutral wire.
In an electrical circuit, the black wire is typically considered hot.
