The voltage of clouds is `4 xx 10^(6) V` with respect to ground. In a lighting strike lasting `100 ms`, a charge of `4 C` is delivered to the ground. The power of ligthing strike isA. `160 MW`B. `80 MW`C. `20MW`D. `500 kW` |

Answer» Correct Answer - a Work done in delivering `g` coulomb of charge from clouds to ground. `W=Vq` `=4xx10^(6)xx4` `=16xx10^(6)J` The power of lighting strike, `P=(W)/(t)=(16xx10^(6))/(0.1)= 160xx10^(6)W= 160MW` |
