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 MW

Text Solution

Verified by Experts

The correct Answer is:
A
Work done = charge `xx` potential difference
If `=4xx(4xx10^(6)-0)=16xx10^(6)J`
Power of the lightening strike `P=-(IV)/(t)`
`=(16xx10^(6))/(100xx10^(-3))=160 MW`
