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
Correct Answer: B
Solution :
According to energy conservation, energy remains the same Þ \[{{U}_{parallel}}={{U}_{series}}\]Þ\[\frac{1}{2}(nC){{V}^{2}}=\frac{1}{2}\left( \frac{C}{n} \right)\,V{{'}^{2}}\]Þ V' = nV (\[V'\]= potential difference across series combination)You need to login to perform this action.
