What is a voltage?

Question

i read that skin produces voltages of electricity. can you have like 20 tons of skin in a jar and have them produce voltage to power a city?

i know i really need to take a physics class

Answer 1

Voltage measurements on the skin of a living person can come from 3 sources.

1. The electrical signals of the nervous system.

2. Chemical reactions between your sweat, and the metals f the electrodes on the device used to measure voltage. In this case you are just working like a battery, but you can't get any useful energy this way.

3. Static electricity from clothes rubbing on skin or each other.

A Voltage is a difference in electrical charge between two places. The difference in charge creates a pressure on invisible particles called electrons. This pressure can cause them to move and his movement is called a current.

Answer 2

I have never heard of this skin voltage thing that you say you have read. I might need a class in biology. To power something like a city you would need a lot of voltage and specially a lot of current. Both go hand in hand. I have not seen the skin power an LED and that only requires .o4amps and .8 volts.

Answer 3

You have been watching Matrix too many times.

skin doesn't produce electricity.

nerves produce a tiny fraction of a volt, but only in a living body.
