Question

In the circuit shown in the figure 1, the battery and the inductor have no appreciable internal resistance and there is no current in the circuit.

1. Immediately after the switch is closed, find the reading of the ammeter A.

2. Immediately after the switch is closed, find the readings of the voltmeters (V1 and V2) .

3. Find the reading of the ammeter A after the switch has been closed for a very long time.

4. Find the readings of the voltmeters (V1 and V2) after the switch has been closed for a very long time.

Explanation / Answer

a) I = 0.... b) V1 = 0, V2 = 25V..... c) 1.667 A..... d) V1 = 25 V, V2 = 0
