Question:
if static electricity produces high voltages why isn't it harmful to people? how is it different from transformers and other sources which also produce high voltage but are harmful?


Replies:
Static electricity is harmful when enough current is involved, e.g., a bolt of lightning.

Tim Mooney


The current in static electricity is extremely low, on the order of a pico amp (1/1000000000000). Involuntary muscle contractions (can't let go!) occurs at about 10 milliamps (10/1000). Clearly, the current in a typical static discharge is far below this level. In a transformer, ther is the possibility of 1000 amps or more. This may very well be lethal.
