\[n\] identical condensers are joined in parallel and are charged to potential\[V\]. Now they are separated and joined in series. Then the total energy and potential difference of the combination will be [MP PET 1993]

• A.                    Energy and potential difference remain same
• B.                    Energy remains same and potential difference is \[nV\]
• C.                    Energy increases \[n\] times and potential difference is \[nV\]
• D.                    Energy increases \[n\] times and potential difference remains same
