A capacitor of capacity `C` is charged to a potential difference `V` and another capacitor of capacity `2C` is charged to a potential difference `4V`. The charged batteries are disconnected and the two capacitors are connected with reverse polarity (i.e. positive plate of first capacitor is connected to negative plate of second capacitor). The heat produced during the redistribution of charge between the capacitors will be

A capacitor of capacitance 5 muF is charged to a potential difference of 10 volts and another capacitor of capacitance 9 muF is charged to a potential difference of 8 volts. Now these two capacitors are connected in such a manner that the positive plate of one is connected to the positive plate of other. Calculate the common potential difference across the two capacitors.

A capacitor C is charged to a potential difference V and battery is disconnected. Now if the capacitor plates are brough close slowely by some distance:

A parallel plate capacitor of capacitance C is connected to a battery and is charged to a potential difference V. Another capacitor of capacitance 2C is ismilarly charged to a potential difference 2V. The charging battery is now disconnected and the capacitors are connected in parallel to each other in such a way that the poistive terminal of one is connected to the negative terminal of the other. The final energy of the configuration is

A capacity of capacity C_(1) is charged up to V volt and then connected to an uncharged capacitor of capacity C_(2) . Then final potential difference across each will be

A capacitor of capacitance C is charged to a potential difference V_(0) . The charged battery is disconnected and the capacitor is connected to a capacitor of unknown capacitance C_(x) . The potential difference across the combination is V. The value of C_(x) should be

A capacitor C is charged to a potential V by a battery. It is then disconnected from the battery and again connected with its polarity reversed to the battery

A capacitor of capacity C charged to potential "V" and " then connected to an identical uncharged capacitor then loss of energy is
