A) \[2.5\times {{10}^{-8}}J\]
B) \[3.5\times {{10}^{-6}}J\]
C) \[2.5\times {{10}^{-4}}J\]
D) \[3.5\times {{10}^{-4}}J\]
Correct Answer: B
Solution :
(b) \[3.5\times {{10}^{-6}}J\] Here, \[C=700\,pF=700\times {{10}^{-12}}F,\,V=100V\] Energy stored,\[U=\frac{1}{2}C{{V}^{2}}\] \[=\frac{1}{2}\times 700\times {{10}^{-12}}\times {{\left( 100 \right)}^{2}}\] \[=3.5\times {{10}^{-6}}J\]You need to login to perform this action.
