A capacitor of capacitance C is connected to a battery of emf V through a resistance R with a switch connected in series .Switch is turned on at t=0 . Find the displacement current flowing between the plates of capacitor as a function of time .

Two capacitors C_(1) and C_(2) are connected with two batteries of emf epsilon_(1) and epsilon_(2) . The circuit components are connected with a switch S as shown in. Initially the switch is open and the capacitors are charged. Find the heat produced when switch S is closed. .

In the circuit shown in fig. when the switch is closed, the capacitor charges with a time constant

Two capacitors C_(1) and C_(2) = 2C_(1) are connected in a circuit with a switch between them as showu in the figure- 3.302. Initially the switch is open and C_(1) holds charge Q. The switch is closed. In steady state, the charge on the two capacitors will be given as :

In the circuit shown, the capacitor is initially uncharged. The switch S is closed at t = 0. Time after which voltage across capacitor and resistor are equal is:

Initially the capacitor is uncharged find the charge on capacitor as a function of time, if switch is closed at t=0.
