What is short circuiting ? State one factor or condition that can lead to it ?
If sometimes a live wire touches neutral wire or earth wire, a large current flows through the circuit due to almost zero resistance of the circuit. This is called short-circuiting. To save the circuit from damage feared due to over-loading or short circuiting, a fuse of proper rating is put in each circuit.
if the low quality of wires are used then, there is a great chance that insulating covering of wire melts and short circuiting occurs
When live and constant wire comes in direct contact is called short circuiting.
