A) CV
B) \[\frac{1}{2}nC{{V}^{2}}\]
C) \[C{{V}^{2}}\]
D) \[\frac{1}{2n}C{{V}^{2}}\]
Correct Answer: B
Solution :
Energy stored by any system of capacitors is \[=\frac{1}{2}{{C}_{eq}}{{V}^{2}}\] where, V is source voltage. Thus, n capacitors are connected in parallel. So, \[{{C}_{eq}}=nC\] \[\therefore \] \[{{E}_{eq}}=\frac{1}{2}nC{{V}^{2}}\]
