Assume that the top globe of a Van de Graff generator (which we can model as a sphere 30 cm in diameter) is charged to the maximum potential of it can have relative to infinity without causing the air surrounding it to break down. A person whose skin is dry has a resistance of about 10,000 Ω. Assume that a person suddenly touches the globe while it is charged. Estimate the maximum current that flows through the person to the ground and the approximate time during which the current flow is significant. A 50 mA current maintained for more than a few seconds can kill a person. Is someone who touches such a globe risking death?
