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

Verified by Experts

Given, Power of the oven (p) = 2kw = 2 x `10^(3)` w
Voltage supplied (V) = 220V
Power = V x I
I = P/V = 2 x `10^(3)`/220 = 9.09 A
Since the domestic electric circuit has a current rating of 5A the flow of 9.09. A by the oven exceeds the safe limit. Here, fuse will blow and break the circuit
