Question

An electric kettle consumes 1 kw of electric power when operated at 200 V. A fuse wire of what rating must be used for it?​

Answer 1

Answer:

Given, power, P = 1 kW = 1000 W Voltage, V = 220 V Current, I = ? Thus, the rating of fuse-wire is 5 A which is greater than 4.5 A.

Power(p)=1000 W. I=1000/220=100/22=4.5 A. So,5 A fuse is required to prevent short circuiting.
