Direction: A coil of inductance 10 H and resistance 40 Ω is connected as shown in the figure. After the switch S has been in contact with point 1 for a very long time, it is moved to poin 2 at t = 0.
-
For the value of obtained in (a), the time taken for 95% of the stored energy to be dissipated is close to—
-
- 0·10 sec
- 0·15 sec
- 0·50 sec
- 1·0 sec
Correct Option: B
| = L Req = | = | Req | 60 |
| = | 0·15 sec | 6 |
Req = 20 + 40
= 60Ω
