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

`20MW`

D

`500 kW`

Text Solution

Verified by Experts

The correct Answer is:
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`
