In the circuit shown in figure, the switch S is closed at time t = 0. The voltage across the inductance at t = 0+, is—
-
- 2V
- 4V
- – 6 V
- 8V
Correct Option: B
The given circuit
at t = 0+ capacitor is replaced by short circuit and inductor is replaced by open circuit. The given circuit can be redrawn as
| Now, VL (0+) = | = 4V | 2 + 3 |
Hence alternative (B) is the correct choice.
