Hi all,

I came across this question whilst doing some homework on capacitors and I could not answer it, despite using the hint. Can someone help me please?

Question
Estimate the capacitance and energy stored in a typical thundercloud.Hint: model the thundercloud and the Earth as a parallel plate capacitor.

Thank you!

Have you tried estimating the area of the base of a thundercloud - these are also known as cumulonimbus clouds http://www.metoffice.gov.uk/learning...s/cumulonimbus

If you live in the UK you'll have seen a lot of these, might be considered an unfair question to ask people from very dry countries I suppose.

I live in the UK.

Would 100m^2 be unreasonable, if it were to be 25m*4m?

These clouds are usually several miles across. You need to think town-sized at least rather than garden-sized.

I was guesstimating the base area was between 1km x 1km and 3km x 3km square i.e. 1 x 10^6 to 9 x 10^6 m2

These are the giant, as seen from orbit by ISS astronaut size cloud type.
