An electric kettle consumes `1 kW` of electric power when operated at `220 V`. A fuse-wire of what rating must be used for it ?

A

1A

B

2A

C

4A

D

5A

Verified by Experts

The correct Answer is:
D
given that,
power=P=1 kW=1000 W
Voltage = V =220
Now, `I=P/V=1000/220=4.5 A`
Now rating of fuse wire must be slightly greater than 4.5 A, that is, 5 A.
