The mutual inductance of two coils \({C}_1\) and \({C}_2\) is 20 mH . In coil \({C}_1\) , the current changes from 4 A to zero in 0.2 s . If the resistance of coil \({C}_2\) is \(4 \Omega\) , then the charge that flows through it per second will be:
- 4.0 C
- 1.5 C
- 0.05 C
- 0.1 C
Answer
(C) 0.05 C
