Question

what is the voltage of electrical impulses in human bodies

Answer 1

A human body can only generate between 10 and 100 millivolts [source: NanoMedicine]. A cathode ray tube requires about 25,000 volts to create a picture on a TV [source: Physics Factbook]. If the machines could gather millions of electric eels, on the other hand, they'd be well juiced up.

Answer 2

20 to 100
20 to 100 microvolt
