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 is

A

160 MW

B

80 MW

C

20 MW

D

500 kW

Text Solution

Verified by Experts

The correct Answer is:
A
Work done in delivering q coulomb of charge from clouds to ground.
`W=V_(q)=4xx10^(6)xx4`
`=16xx10^(6)J`
The power of lightning strike is
`P=(W)/(t)=(16xx10^(6))/(0.1)=160xx10^(6)W`
`=160 MW`
