What is ESD - Electrostatic Discharge Safety, Prevention, Eliminate

A man sitting near a high-voltage source (likely a Van de Graaff generator or a similar electrostatic device). Because the voltage is high but the current (amperage) is very low, it isn't lethal, but it creates a powerful electric field. This causes his hair to stand on end as each strand becomes positively charged and repels the others. The "jump" at the end occurs when a discharge happens or the man's movement causes a sudden shift in the electrical potential, leading to a startling (though us
