Answer 1

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

Explanation:

The fuse is connected in the live wire before the switch so that, if the circuit is overloaded, the fuse melts and immediately cuts off the supply. This protects the appliance and the user from excess current.
