Question

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

In the circuit shown in the figure , the battery and the inductor have no appreciable internal resistance and there is no current in the circuit. Immediately after the switch is closed, find the reading of the ammeter A and Voltmeters(V1 and V2) Find the reading of the ammeter A after the switch has been closed for a very long time. A and Voltmeters(V1 and V2)

Explanation / Answer

A) imeediately after closing I = 0

V1 = 0 V2 = 25


B) after a long time inductor runs out

I = 25/15 =1.67 A

V1 = 25

V2 = 0
