An isolated capacitor of unknown capacitance has been charged to potential `V_(0)`. This capacitor is then connected to an uncharged capacitor of capacity C. If common potential is `V(ltV_(0))`, find unknown capacitance.

A capacitor of capacitance C_1 is charged upto potential V and then connected in parallel to an uncharged capacitor of capacitance C_2 . The final potential difference across each capacitor will be

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.

A capacitor of capacitance 50 muF is charged to a potential of 1,000 V. Calculate the energy stored in the capacitor.

A 10 muF capacitor is charged to a potential difference of 50 V and is connected to another uncharged capacitor in parallel. Now the common potential difference becomes 20 volt. The capacitance of second capacitor.
