Lightning is a bright flash of electricity produced by a thunderstorm. All thunderstorms produce lightning and are very dangerous. Lightning is an electric current: a natural phenomena and a typical one may transfer 109 J of energy across a potential difference of 50,000,000.00 V during a time interval of about 0.2 s. With the information given, calculate the total amount of charge transferred between the cloud and the ground, the current of lightning bolt, and the average power delivered over 0.2 s time.

Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.
