Question

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

(a) 5 A
(b) 3 A
(c) 1 A
(d) 2 A

Answer 1

(d) 2 A
It is given that:
Power, P = 230 W
Potential difference, V = 230 V
Therefore, current, I = P / V = 230 / 230 = 1 A
So, the correct option is 2 A because the value of fuse used by any appliance should be slightly larger than the value of normal current drawn by it.
