Aquestion for the physicists out there:
during a thunderstorm, the potential difference between the thunderclouds and the ground builds up to v. in each stroke of lightning, 30c of charge passes between the thunderclouds and the ground. lightning strokes to the ground occur, on average, and 2 minute intervals.
calculate:
i) the average current between the thunderclouds and the ground,
ii) the energy transferred in each stroke of lightning.
i already know the answer, i'm just seeing who here is good at physics ; )
