Question

A fuse should always be placed in the
(a) Live wire of the main circuit
(b) Neutral wire of the main circuit
(c) Earth wire of the main circuit
(d) Bothe live and neutral wire of the main circuit.​

Answer 1

Explanation:

Option A

Live wire of the main circuit

because if the fuse is put in the neutral wire, then due to excessive flow of current when the fuse burns, current stops flowing in the circuit, but the appliance remains connected to the high potential point of the supply through the live wire.
