Question

Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maximum rate of charge flow in a lightning bolt is about 20,000C/s; this lasts for 100μs or less. How much charge flows between the ground and the cloud in this time?

Answer 1

2C charge will flow from ground and cloud

Step-by-step explanation:

We have given rate rate of flow of charge
`(dq)/(dt)=20000C/sec`

Time is given as
`t=100\mu sec=100* 10^(-6)=10^(-4)sec`

WE have to find the how much charge flows between the ground and cloud in this time

So the charge flow is given by
`(dq)/(dt)* t=20000C/sec* 10^(-4)=2C`

So 2C charge will flow from ground and cloud
