CAPACITOR

The enrgy of a charged capacitor is U. Another identical capacitor is connected parallel to the first capacitor, after disconnecting the battery. The total energy of the system of these capacitors will be

A battery of 20V is connected to a capacitor of capacitance 10 muF . Now battery is removed and this capacitor is connected to a second uncharged capacitor. If the charge distributes equally on these two capacitors, the total energy stored in the two capacitors will be

A battery is used to charge a parallel plate combination of two identical capacitors. If the potential difference across the battery is V and the total charge Q flows through the battery during the charging process then 1) The charge on each capacitor is Q/2 and the potential of each capacitor is V/2 2) The charge on each capacitor is Q and the potential of each capacitor is V 3) The charge on each capacitor is Q/2 and the potential of each capacitor is V 4) The charge on each capacitor is Q and the potential of each capacitor is V/2

If three capacitors are connected in a parallel capacitor network then, Choose the correct statements out of the following: (l) Potential difference across each capacitor is same. (II) For each capacitor, charges is different (III) Voltage applied is different for each capacitor. (IV)For each capacitor, charges are same.

A battery of 10V is connected to a capacitor of capacity 0. lF . The battery is now removed and this capacitor is connected to a second uncharged capacitor. If the charges are distributed equally on these two capacitors, find the total energy stored in the two capacitors. Find the ratio of final energy to initial energy stored in capacitors.
