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.
Homework Answers
current = charge / time
charge = I*t
= 20000*100*10^-6
= 2 C
so the charge flowing is 2 C

11a) A heavy summer rain has just spoiled a fun game of frisbee between you and your friends. As you rush to leave, a bolt of lightning strikes a tree on the other side of the field. Lightning is a form of electrical discharge that occurs when the electric field in a region between the ground and the clouds ionizes the air. You happen to know that a bolt of lightning can unleash about five hundred million joules of energy,...

The electrical breakdown of an insulator occurs when an electric field becomes large enough to ionize the insulator, allowing electrical current to flow; lightning is an example of the electrical breakdown of air. The electrical breakdown of air occurs when the electric field reaches about 3×106 N/C . Estimate the magnitude of the total static charge on your body ?body
