उत्तर
Both A and R are true and R is correct explanation of the assertion.
Explanation:
The assertion is true because a fuse must be in series to monitor the total incoming current. The reason is also true because excess current generates heat that melts the fuse wire. Since melting the series connection safely stops current flow to all appliances, the reason correctly explains the assertion.
