Question

An electric oven of 2kw is operated in a domestic electric circuit (220v) that has a current rating of 5A. What result do you expect? Expalin​

Answer 1

Answer:

Fuse wire will break.

Explanation:

Power is given by :-

P=VI

=> I=P/V

For the current scenario, P=2kW= 2000W and V=220V

Hence, I=2000/220 = 200/22 = 9.09A

This shows that the oven draws a current of 9.09 A whereas the fuse has a limit of 5A. Due to the excess current, the fuse will melt.
