Question

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?

Answer 1

Step-by-step explanation:

Given

maximum rate of flow is
`\frac{\mathrm{d} i}{\mathrm{d} t}=20,000\ C/s`

Time of flow
`t=100\ \mu s`

Charge flows during this process

`=\frac{\mathrm{d} i}{\mathrm{d} t}* t`

`Q=20,000* 100* 10^(-6)`

`Q=2\ C`

(b)Total no of electron(n)

If charge on one electron is
`q=1.6* 10^(-19)`

`n=(Q)/(q)=(2)/(1.6* 10^(-19))=1.25* 10^(19)`
