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?



(a) 1 a



(b) 2 a



(c) 4 a



(d) 5 a

Answer 1

a fuse wire of 2a rating must be used for it

Answer 2

Answer:

given:-p = 1 K W which is=1000W

V=220V

Now P=VI

therefore I = P/V

I=1000/220= 4.5A

therefore the rating must be either 4.5A or 5A.
