Question
The voltage of clouds is 4 × 106 volt with respect to round. In a lighting strike lasting 100msec, a charge of 4 coulombs is delivered to the ground. The power of lightening strike is :
Options
A.160 MW
B.80 MW
C.20 MW
D.500 MW
Solution
Energy delivered to the ground
= 4 × 106 × 4 = 16 × 106 joule
Power =
= 16 × 107
= 160 MW
= 4 × 106 × 4 = 16 × 106 joule
Power =
= 16 × 107= 160 MW
