Given: P = 2 kW = 2000W and V= 220 volts, I =?
Applying the formula P = Vl, we get
I = \(\frac{P}{V}\) = \(\frac{2000}{220}\)
= 9 A
Since the current flowing (9 A) through the circuit is more than the current rating (5 A) of the circuit, so the fuse in the circuit will melt and circuit is broken but electric oven is saved from getting damaged.
