In the circuit shown in the figure, `E = 50.0 V, R = 250 Omega` and `C = 0.500 muF.` The switch `S` is closed for a long time, and no voltage is measured across the capacitor. After the switch is opened, the voltage across the capacitor reaches a maximum value of `150 V`. What is the inductance `L`?

In the circuit shown in fig, switch S was closed for long time. At time t-0, teh switch is opened again. The maximum potential difference across teh plates of the capacitor after the switch is opened is

The switch is closed at t=0. Find time after which voltage across capacitor becomes 50 V. (take ln 2 = 0.6)

The switch is closed for a long time and then opened at time t = 0. Find the initial voltage across L after t = 0, which end is at higher potential P or Q?

In the circuit in Fig. switch S_(1) was closed for a long time . At time t = 0 the switch is opened. Find the maximum potentail difference across the plates of the capacitor after the switch is opened.

In the circuit shown in figure, E = 120 V, R_1 = 30.0Omega, R_2 = 50.0 Omega and L=0.200H . Switch S is closed at t = 0 . Just after the switch is closed.
