As a man move about in a dry atmosphere, electric charge accumulates on the man's body. Once it is at high voltage, either negative or positive, the body can discharge via shocks and sparks. Consider a human body isolated from ground, with the typical capacitance 180 pF.
(a) Find what charge on the body will produce a potential of 12.0 kV?
µC
(b) Sensitive electronic devices can be destroyed by electrostatic discharge from a man. A particular device can be destroyed by a discharge releasing energy of 255 µJ. Find to what voltage on the body does this situation correspond?
kV
