A) 8 J
B) 16 J
C) \[4\times {{10}^{-3}}\text{J}\]
D) \[2\times {{10}^{-3}}\text{J}\]
Correct Answer: A
Solution :
Given \[C=1\mu F,\,V=4000volt.\] Energy stored in the capacitor, \[U=\frac{1}{2}C{{V}^{2}}\] \[=\frac{1}{2}\times 1\times {{10}^{-6}}\times {{(4000)}^{2}}\] \[=8J.\]You need to login to perform this action.
