Electromagnetic Induction

Question:

A uniformly wound solenoid coil of self inductance 1.8 ´ 10–4 henry and resistance 6 ohm is broken up into two identical coils. These identical coils are then connected in parallel across a 15-voll battery of negligible resistance. The steady state current through the battery is

Options:

8A

4A

5A

6A

Correct Answer:

8A

Explanation:

The steady state current in the circuit is 

$ I = \frac{E}{R} = 8A$
