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 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 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

A capacitr is charged from a dc source through a resistance of 3MOmega . If the potential difference across it reaches 75% of its final value in half a second, find its capacitance.

A capacitor charges from a cell through a resistance. The time constant is tau . In what time will the capacitor collect 10% of the final charge?

A capacitor of capacitance 200 muF is connected to a battery through a resistance of 5 kOmega at time t = 0. Charge stored in the capacitor in first second in larger than the charge stored in the next
