A) CV
B) \[\frac{1}{2}nC{{V}^{2}}\]
C) \[C{{V}^{2}}\]
D) \[\frac{1}{2n}C{{V}^{2}}\]
Correct Answer: B
Solution :
| [b] 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, \[{{C}_{eq}}=nC\] |
| \[\therefore \] \[{{E}_{eq}}=\frac{1}{2}nC{{V}^{2}}\] |
