Electricity Basics: Amps

(page 1 of 7)

What is an Amp?

Simply stated, an Amp is the measure of the flow of electrons (usually through a wire).   

When a voltage is produced (from a solar panel, a generator, etc) it creates a force that pushes electrons through a conductor creating a current.   One amp of current is approximately equal to 6.25 X 10^18 of electrons per second.

Amps can be compared to the flow of water through a pipe (which is the measure of the flow of water molecules).   Water flow is usually measured in gallons per minute, and electron flow is measured in amps.
