A) \[2\times {{10}^{-2}}\]
B) \[4\times {{10}^{-2}}\]
C) \[4\times {{10}^{4}}\]
D) \[4\times {{10}^{10}}\]
Correct Answer: B
Solution :
Heat produced in a wire is equal to energy stored in capacitor. \[H=\frac{1}{2}C{{V}^{2}}=\frac{1}{2}\times (2\times {{10}^{-6}})\times {{(200)}^{2}}\] \[={{10}^{-6}}\times 200\times 200\] \[=4\times {{10}^{-2}}J\]You need to login to perform this action.
