A charged condenser is made to share its charge with an uncharged condenser of twice its capacitance. Find the sum of the energy of the two condensers?

A 0.1F capacitor is charged by a 10V battery. After disconnecting the battery, this charged capacitor is connected with an uncharged capacitor. If the charge is equally shared between the two, then what will be the energy stored in the two capacitors? Compare this energy with the energy stored initially in the first capacitor.

A capacitor of capacitance 2 mu F is charged with 20 V potential. Another uncharged capacitor of capacitance 3 mu F is connected parallely with the first capacitor. What will be the potential difference at the two ends of the combination? Calculate the amounts of charge of the capacitors.

Two plates of an isolated charged capacitor are connected by a copper wire. What will happen to the energy stored in the capacitor?

A potential difference of 20V is applied across a parallel combination of three identical capacitors. If the total charge in the combination be 30C, determine the capacitance of each capacitor. What will be the charge in the series combination of these three capacitors with the same potential difference?
