At `t=0` switch `S` is closed . Find
`(a) charge on capacitor after one time constant
(b) the time when p.d. across resistance equals p.d. across capacitance
(c ) maximum energy stored in capacitor.

At t=0 switch S is closed . (a) After how much time , charge on capacitor is 50% of maximum charge stored on capacitor. (b) After how much time, energy stored in capacitor is halt of maximum energy stored in capacitor.

During charging of capacitor find time when potential drop across capacitor is equal to potential drop across resistance :-

The switch is closed at t=0. Find time after which voltage across capacitor becomes 50 V. (take ln 2 = 0.6)

In the circuit shown in fig, if the switch S is closed at t = 0 , the capacitor charges with a time constant

For the given capacitor configuration (a) Find the charges on each capacitor (b) potential difference across them ( c) energy stored in each capacitor .

A capacitance C , a resistance R and an emf (epsilon) are connected in series at t=0.What is the maximum value of (a) the potential difference across the resistor, (b) the current in the circuit,(c )the potential difference across the capacitor, (d) the energy stored in the capacitor ,(e)the power delivered by the battery and (f) the power converted int heat.
