Find heat produced in the circuit shown in figure on closing the switch S .

The capactor C_1 in the figure initially carries a charge q_0 . When the i switch S_1 and S_2 are closed, capacitor C_1 is connected to a resistor R and a second capacitor C_2 , which initially does not carry any charge. (a) Find the charges deposited on the capacitors in steady state and the current through R as a function of time. (b) What is heat lost in the resistor after a long time of closing the switch?

The capacitor C_(1) in the figure initially carries a charge q_(0) . When the switch S_(1) and S_(2) are shut, capacitor C_(1) is connected in series to a resistor R and a second capacitor C_(2) , which initially does not carry any charge. If the heat lost in the resistor after a long time of closing the switch is (q_(0)^(2)C_(2))/(kC_(1)(C_(1)+C_(2))) , then Find the value of k .

Find heaty produced on closing the switch S

For the circuit shown in the diagram find the value of V_a - V_b after long time closing the switch S_1 :

Two long conducting rods suspended by means of two insulating threads as shown in Fig. are connected at one end to a charged capacitor through a switch S, which initially open. At the other end , they are connected by a loose wire. The capacitor has charge Q and mass per unit length of the rod is lambda . The effective resistance of the circuit after closing the switch is R. Find the velocity of each rod when the capacitor is discharged after closing the switch. (Assume that the displacement of rods during the discharging time is negligible.)

Conisder the istuation shown in the figure. The capacitor A has a charge q on it whereas B is unchanged. The charge appearing on the capacitor B a long time after the switch is closed is

In the circuit shown in fig switch S is closed at time t =0. a. What is the current I_(0) leacing the battery at t=0, immediately after the switch is closed? b. What is the current I "long time" later? c. What charge has accmulated on the capacitor after this long time? d. If, finally, swtich S is opened again, how long will it take after the switch is opened for the capactior to lose 80% of its charge?

Find how the voltage across the capacitor C varies with time t after closing of the switch S_(w) at the moment t=0 . .
