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
Text Solution
Verified by ExpertsThe correct answer is:
B
According to energy conservation, energy remains the same
⇒ ⇒ 
⇒ ⇒ 
⇒ ⇒ V' = nV
( 
= potential difference across series combination)
