Lightning occurs when there is a flow of electrons between the ground and thethunder cloud. the maximum rate of flow (current) is about 20,000 c/s (amps), andit lasts for about 100 microseconds. how much charge flows between the groundand the cloud in this time? how many electrons flow during this time?

Explanation:
Given
maximum rate of flow is![\frac{\mathrm{d} i}{\mathrm{d} t}=20,000\ C/s](/tpl/images/0466/5016/b334a.png)
Time of flow![t=100\ \mu s](/tpl/images/0466/5016/137a3.png)
Charge flows during this process
(b)Total no of electron(n)
If charge on one electron is![q=1.6\times 10^{-19}](/tpl/images/0466/5016/192e8.png)
