• 2 A

Answer 1

A TV set consumes an electric power of 230 watts and runs on 230 volts mains supply. The correct fuse for this TV set is 2 A.

Explanation:

Given: Power (P) = 230 Watts

Voltage (V) = 230 volts

We know that,

I = `P/V`

⇒ I = `230/230`

⇒ I = 1 A

A 2 A fuse is the next higher standard rating that safely allows normal operation while protecting against faults.
