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 when you generate a static spark with your fingertip when getting out of your car. Assume a spark gap of 1 mm.
