Question

In a lightning strike, a charge (q) of 18 C is transferred between a cloud and the ground in a time of 2.0x10^-2 at a potential difference of 1.5x10^6 volts. What is the average current produced by the strike?

Answer 1

$current =\frac{charge \ transferred}{time }=\frac{18}{2\times10^{-2}}=900 A$
