Question

Assume that global lightning on the Earth constitutes a constant current of 1.00 kA between the ground and an atmospheric layer at potential 310 kV.

(a) Find the power of terrestrial lightning.
? =  W
(b) For comparison, find the power of sunlight falling on the Earth. Sunlight has an intensity of 1300 W/m² above the atmosphere. Sunlight falls perpendicularly on the circular projected area that the Earth presents to the Sun.
? =  W
