In the circuit shown below, the switch is closed at t=0. The value of  in degrees which will give the maximum value of DC offset of the current at the time of switching is

A DC voltage source is connected to a series L-C circuit by taming on the switch S at time t-0 as shown in the figure. Assume. Which one of the following circular loci represents the plot of i(t) versus v(t)?

In the circuit shown, switch  has been closed for a long time. At time t = 0 switch  is closed. At , the rate of change of current through the inductor, in amperes per second, is _____________.

In the circuit shown in figure switch \(SW_1\), is initially CLOSED and \(SW_2\) is OPEN. The inductor L carries a current of 10A and the capacitor is charged to 10 V with polarities as indicated. \(SW_2\), is initially CLOSED at  and \(SW_1\), is OPENED at t=0. The current through C and the voltage across L at  is

An ideal capacitor is charged to a voltage V0 and connected at t = 0 across an ideal inductor L.  (The circuit now consists of a capacitor and inductor alone).  If we let , the voltage across the capacitor at time t > 0 is given by
