Question :

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?Submitted on 22/2/2024 | Answered by Vandana Rana

Answer :

Given,
Power, P= 1 KW = 1000 W
Voltage, V = 220 V
We know,
Power, P = V I
Putting all the values
1000 = 220 ×I
⇒ I = 1000/220
= 4.54 A
≈ 5 A
Therefore, fuse wire of rating 5 A can be used.
