a capacitor of capacitance `C` is connected to two voltmeter `A` and `B`. `A` is ideal , having infinite resistance, while `B` has resistance `R`. The capcitor is charged and then switch `S` is closed. The reading of `A` and `B` will be equal

A capacitor of capacitance C has charge Q. it is connected to an identical capacitor through a resistance. The heat produced in the resistance is

A capacitor C is connected to a battery circuit having two switches S_(1) and S_(2) and resistances R_(1) and R_(2) . The capacitor will be fully charged when .

A capacitor of capacitance C_(1) is charged to a potential difference V and then connected with an uncharged capacitor of capacitance C_(2) a resistance R. The switch is closed at t = 0. Choose the correct option(s):

A : potentiometer can act as an ideal voltmeter . R : An idea, voltmeter has infinite resistance .

A capacitor of capacitance as C is given a charge Q. At t=0 ,it is connected to an ideal battery of emf (epsilon) through a resistance R. Find the charge on the capacitor at time t.

Four capacitors of capacitance C , 2C , 3C & 4C respectively are connected as shown in figure. Battery is deal and all the connected wires have no resistance capcitance or inductance. Initially the switch S is open. If at t=0 switch S is closed The charge flown through connector AB after switch is closed is
