The voltage of clouds is `4xx10^(6)V` with respect to ground. In a lightning strike lasting `0.1s`, a charge of 4 C is delivered to the ground. The power of the lightning strike is

A

160 MW

B

80 MW

C

20 MW

D

500 MW

Text Solution

Verified by Experts

The correct Answer is:
A

`because V=(W)/(Q)" "therefore` W=V`xxQ=4xx10^(6)xx4J`
`therefore`Power`=(W)/(t)=(4xx10^(6)xx4)/(0.1)`
`=16xx10^(7)W=160xx10^(6)W=160MW`

(b) What is the energy spent in the lightning if it lasts for 0.001 s ? ( c) What is the approximate cost of a lightning discharge ? (d) What message did nature convey to the man through lightning ?

The graph given here represents an idealized sinusoidal current flow between a cloud at a height of 1 km and the earth, during a lightning discharge. Value of I_(0) is 157 kA and T = 0.2 ms. Assume that discharge happens when the electric field in the air between the cloud and the earth becomes equal to the breakdown field of air i.e., E_(0) = 3 xx 10^(6) V//m (a) Calculate the total charge flow due to lightning. (b) Calculate the average current between the cloud and the earth during the lightning. (c) Assume that the entire charge on the cloud is released during the lightning and estimate the capacitance of the cloud – Earth system.

In the return stroke of a typical lightning bolt, a current of 2.8 xx 10^(4)A exists for 20 mu s . How much charge is transferred in this event ?
