Can a capacitor be charged to any potential of high value? Explain.

A 2muF capacitor is charged to a potential of 20V. Another 3muF uncharged capacitor is connected in parallel with the first capacitor. What would be the terminal potential difference of the combination? Find out the charges on the two capacitors?

A 20muF capacitor is charged to a potential of 20V and is then connected to an uncharged 10muF capacitor. Find out the common potential and the ratio of the energies stored in the two capacitors.

A capacitor C_1 of capacitance 5muF is charged to a potetntial of 100V and another capacitor C_2 of capacitance 8muF is charged to 50V. The positive and negative plates are mutually connected. The final potential of the combination of the two capacitance will be

A parallel plate capacitor of capacitances C is connected to a battery to charge it to a potential V. Similarly, another capacitor of capacitance 2C is charged to a potential 2V. Now the batteries are removed, and the two capacitors are connected in parallel by joining the positive plate to one with the negative plate of the other. Find out the final energy of the system.

A capacitor of capacitance C is charged to a potential difference V from a cell and then disconnected from it. A charge +Q is now given to its positive plate. The potential difference across the capacitor is now

A capacitor is charged through a potential difference of 200 V, when a charge of 0.1 C is stored in it. How much energy will it release when it is discharged?

A parallel plate capacitor of capacitance C is charged to a potential V. It is then connected to another uncharged capacitor having the same capacitance. Find out the ratio of the energy stored in the combined system to that stored initially in the single capacitor.
