An electric oven of 2 kW power rating is operated in a domestic electric circuit (220 V) that has a current rating of 5 A. What result do you expect? Explain.

The current drawn by the electric oven can be calculated using the formula

P = V × I

I = P/V

On putting the values, we get

I = 2000 W/220 V = 9.09 A

The current drawn by the electric oven is 9.09 A, which is higher than the circuit’s safe limit. As a result, the fuse melts and the circuit is broken.
