A question for the physicists out there:
During a thunderstorm, the potential difference between the thunderclouds and the ground builds up to [tex]1.5*10^6[/tex] 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 ;)
I don't think that's exactly what this website is here for. / / / The average current = 30 C / 120 sec = 250 mA. / / / 1 volt = 1 joule/coulomb ... 30 C x 1.5 x 10^6 J/C = 4.5 x 10^7 joules per stroke. / / / Apoligies for the formatting. Some websites recognize a CR-LF from a mobile device, and others don't.
