Can an iron nail replace a wire in a circuit?

An iron nail can replace a short length of wire in a circuit if the points of contact of the nail to the rest of the circuit have no rust or corrosion and good connection can be made. Using solder to join the nail to the circuit can help make a good connection. However, if this is for a scientifically controlled experiment fine as long as its very low voltage. If you are considering high voltage . DO NOT ATTEMPT IT. Its extremely dangerous


how many rooms are allowed on one lighting circuit?

Unless you do not have enough space in the service panel it is always a good idea to have each room on it's own circuit. If you want to put 2 rooms on a circuit just make sure those 2 rooms do not overload the circuit and wire it for a 20 amp circuit. Two bedrooms with 8 outlets each and 1 light each is about all you would want on the circuit. I would never put 3 rooms on the same circuit.


Why is it good to a ground on a receptacle?
