| Q.13 | There are two coils having coefficient of coupling 0.8. The current in coil 1 is 2 A and the total flux 0.4 m Wb. The voltage induced in coil 2 is 50 volts when the current in coil is reduced to zero in 2 m sec. The no of turns in coil 1 is 300. So, the value of mutual inductance M will be: | |
| Ans | 1. 5 H | |
| 2. 0.05 H | ||
| 3. 0.5 H | ||
| 4. 50 H |
Correct Ans Provided: 2
