One of the scientists, speaking from personal experience, said that a person probably wouldn’t feel a difference between a shock of 500 volts and anything higher. “It just hurts,” he says. High voltage but low amperage.
Amber. William Gilbert, an English physician, physicist and natural philosopher, used amber to study static electricity.
True. William Morrison of Des Moines, Iowa built the first successful electric automobile in the United States in 1891. In 1900 about one-third of all cars found on the roads of New York City, Boston, and Chicago were electric.
