Suppose that global lightning on the Earth constitutes a constant current of 1.00 kA between the ground and an atmospheric layer at potential 260 kV.
(a) Determine the power of terrestrial lightning.
p= ________ W
(b) For comparison, determine the power of sunlight falling on the Earth. Sunlight has an intensity of 1400 W/m2 above the atmosphere. Sunlight falls perpendicularly on the circular projected area that the Earth presents to the Sun.
p= ________ W
