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

Answer:

(D) 2A

Explanation:

As per the question, given data,

TV set consumes an electric power =  230 watts

Voltage supplied = 230 volts

As we have,

Power supplied = Voltage × current

⇒ 230 = 230 × I

⇒ I = 1 Ampere

That is,

Maximum current is drawn = 1 Ampere

As we also know that fuse required for any electrical appliances to run is 1.25 times of the maximum current drawn.

So the required current of fuse for the given television set to run properly nearly equal to 2 Ampere.

Hence, the most appropriate correct option is (D).
