In the diagram given below, Coil – 1 is connected in series with a battery and a plug key while Coil – 2 is connected with a galvanometer.
- (i)Why does the galvanometer show deflection only when the key (K) is plugged in and not when a steady current starts flowing in the circuit ?
- (ii)What is observed in the galvanometer, when the key is plugged out ?
- (iii)State the conclusion based on the observation of this activity.
