A) \[17.0\times {{10}^{-8}}J\]
B) \[13.0\times {{10}^{-9}}J\]
C) \[8.7\times {{10}^{-7}}J\]
D) \[6.7\times {{10}^{-7}}J\]
Correct Answer: C
Solution :
Here: capacitance \[C=700\,pF=700\times {{10}^{-12}}F\] Source voltage \[V=50\text{ }V\] Electrostatic energy is given by \[E=\frac{1}{2}C{{V}^{2}}\] \[=0.5\times 700\times 10-12\times {{(50)}^{2}}\] \[=8.7\times {{10}^{-7}}J\]You need to login to perform this action.
