A TV set consumes an electric power of 230 watts and runs on 230 volts mains aupply. The correct fuse for this TV set is: a) 5A b) 3A c) 1A d) 2A

Answer:

Option (d) 2A is the most adequate answer.

Explanation:

Power P is equal to 240 watts.

V = 240V is the voltage.

We already know that power equals voltage times current.

Maximum current drawn I = Power / Voltage = 240/240 = 1A = 240/240 = 1A

The fuse required will have a current rating of 1.25 times the maximum current.

As a result, using a 2A fuse is sufficient for the particular television set.
