Achoke coil is connected across 18 VDC supply and current of 6 A is found to flow through it in steady state. Now the same choke coil is connected to 15 VAC source whose angular frequency is 50 rad /s and current of 3 A is found to flow through it.
(i) Calculate self - inducatance of the coil.
(ii) If a capacitor of 2500 `muF` is connected in series with the coil then calculate power developed in the circuit.

Explanation

To solve the problem step by step, we will break it down into two parts as per the question.

### Part (i): Calculate self-inductance of the coil.

1. **Determine the Resistance (R) using DC supply:**
- Given:
- Voltage (V) = 18 V
- Current (I) = 6 A
