Answer 1

HEY MATE HERE IS YOUR ANSWER:-

If the plastic insulation of the live wire and neutral wire gets torn, then the two wires touch each other. This touching of live wire and neutral wire directly is known as short circuit.

when the two wires touch each other, the resistance of the circuit so formed is very very small. since the resistance is very small, the current flowing in the wires become very large and heats the wire to a dangerous high temperature and fire may be started.
