Current in a circuit falls form 0.5 A to 0.0 A in 0.1 s. If an average e.m.f. of 200 V is induced, give an estimate of the self inductance of the circuit ?

Explanation

To solve the problem, we need to find the self-inductance \( L \) of the circuit given the change in current, the time interval, and the induced electromotive force (e.m.f).

### Step-by-Step Solution:

1. **Identify the given values:**
- Initial current \( I_1 = 0.5 \, \text{A} \)
- Final current \( I_2 = 0.0 \, \text{A} \)
- Time interval \( dt = 0.1 \, \text{s} \)
