In the circuit shown in figure switch s is closed at time t = 0. Find the current through different wires and charge stored on the capacitor at any time t.

In the circuit shown in figure, find the charge stored in each capacitance

In the circuit shown in figure, the battery is an ideal one, w/The emf V. The capacitor is initially uncharged. The switch s is closed at time t = 0 The charge Q on the capacitor at time t is

In the given circuit, the switch K_2 is opened and the switch K_1 is closed at time t=0. At time t=t_0 , the switch K_1 is opened and the switch K_2 is simultaneously closed. Sketch the variation of the inductor current I with time.

The figure shows two identical parallel plate capacitor connected to a battery with the switch S closed. The switch is now opened and the free space between the plates of the capacitor is filled with a dielectric of dielectric constant 3. Find the ratio of the total electrostatic energy stored in both capacitors before and after the introduction of the dielectric.

In the circuit shown below , the switch is kept in position a for a long time and is then thrown to position b. The amplitude of the resulting oscillating current is given by
