An inductor coil of resistance `10 Omega` and inductance 120 mH is connected across a battery of emf 6 V and internal resistance `2 Omega`. Find the charge which flows through the inductor in (a) 10 ms, (b) 20ms and (c ) 100ms after the connections are made.

Explanation

To solve the problem, we will follow these steps:

### Given Data:
- Resistance of the inductor coil, \( R = 10 \, \Omega \)
- Inductance, \( L = 120 \, \text{mH} = 120 \times 10^{-3} \, \text{H} \)
- EMF of the battery, \( \mathcal{E} = 6 \, \text{V} \)
- Internal resistance of the battery, \( r = 2 \, \Omega \)
