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.

Different ways to induce current in a coil are as given below: • If a magnetic field is changed around a coil then an induced current is set up in the coil. It can be done by taking a bar magnet and bringing it closer to the coil or taking it away from the coil. • If a coil is moved in a magnetic fiRead more

The split ring in the electric motor acts as a commutator. The commutator reverses the direction of current flowing through the coil after each half rotation of the coil. Due to this reversal of the current, the coil continues to rotate in the same direction. For more answers visit to website: httpsRead more
