Question

what is a short circuit? what are the causes of short circuit​

Answer 1

over loading can occur when the live wire and the neutral wire come into direct current. In such situation,the current in the circuit abruptly increases it is called as the short circuting.

Answer 2

Answer:

A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circuit. The opposite of a short circuit is an "open circuit", which is an infinite resistance between two nodes.
