A capacitor of 2µF is charged as shown in the diagram. When the switch S is turned to position 2, the percentage of its stored energy dissipated is:

Text Solution
Verified by ExpertsThe correct answer is:
A
Initially, the energy stored in
capacitor is

Initially, the charge stored in
capacitor is
coulomb. When switch S is turned to position 2, the charge flows and both the capacitors share charges till a common potential
is reached


Finally, the energy stored in both the capacitors

loss of energy,
