A capacitor is being charged from a battery through a `2M Omega` resistor. If it takes 0.5 s for charge to reach half its final value, what is the capacitance of the capacitor ?

A capacitor is being charged from dc source through a resistance of 5M Omega . If it takes 0.5s for charge to reach three-quarters of its final value, what is the capacitance of the capacitor ?

A capacitor is charged from a battery through a resistance of 1 M Omega . If it takes 1 sec for the charge to reach one-half of its final value then capacity of capacitor is

An initially uncharged capacitor C is being charged by a battery of emf E through a resistance R upto the instant when the capacitor is charged to the potential E/2, the ratio of the work done by the battery to the heat dissipated by the resistor is given by :-

If charge on the capacitor is doubled the value of its capacitance will be

A capacitor of capacitance 500(mu)F is connected to a battery through a (10 k (Omega)) resistor.The charge stored on the capacitance 2(mu)F are separately charged by a common battery for a long time. The two capacitors are then separately discharged through equal resistors.Both the discharge circuits are connected at t=0.
