Power rating of electric oven P = 2 kW = 2000 W Supply voltage V = 220 V So, the current drawn by electric oven 𝐼 = 𝑃/𝑉 = 200 𝑊/220 𝑉 = 9 𝐴 As the current rating of domestic electric circuit is only 5 A and the oven draws a current 9 A, which is more than the current rating, hence the circuit will bRead more
Power rating of electric oven P = 2 kW = 2000 W
Supply voltage V = 220 V
So, the current drawn by electric oven 𝐼 = 𝑃/𝑉 = 200 𝑊/220 𝑉 = 9 𝐴
As the current rating of domestic electric circuit is only 5 A and the oven draws a current 9 A, which is more than the current rating, hence the circuit will be damaged due to overheating/overloading.
