Correct Answer: A
Solution :
Work done in delivering q coulomb of charge from clouds to ground. \[W=Vq\] \[=4\times {{10}^{6}}\times 4\] \[=16\times {{10}^{6}}J\] The power of lightning strike is \[P=\frac{W}{t}=\frac{16\times {{10}^{6}}}{0.1}=160\times {{10}^{6}}W\] \[=160MW\]You need to login to perform this action.
