A) \[80\text{ }J\]
B) \[0.8\text{ }J\]
C) \[8\times {{10}^{-3}}\]
D) \[8\times {{10}^{-6}}J\]
Correct Answer: A
Solution :
Given, the capacity of capacitor, \[C=10\times {{10}^{-6}}\mu F\] Potential\[V=400\]volt Stored energy = Heat generated \[U=\frac{1}{2}C{{V}^{2}}\] \[=\frac{1}{2}(10\times {{10}^{-6}})\times {{(400)}^{2}}\] \[=\frac{1}{2}\times 10\times {{10}^{-6}}\times 16\times {{10}^{4}}=0.8J\]You need to login to perform this action.
