What is the difference between an AMP, a VOLT, and a WATT?

If we think of electricity as water flowing through a pipe it can help us understand amps, volts and watts:

Amps would be the speed of the volume of water flowing through the pipe.

The water pressure would be the voltage.

Watts would be the power the water could provide (think back to the old days when water was used to power mills).

So with this analogy in mind the definitions below for amp, volt and watt should be easier to understand:

Ampan ampere is the unit for measuring electricity. The accepted standard unit used for measuring how fast an electric current flows is an example of an ampere.  SPEED

Voltthe basic unit of electromotive force (pressure), equal to the electromotive force, or difference in potential, that causes a current of one ampere to flow through a conductor.  FORCE/PRESSURE

Watt the basic unit of electric, mechanical, or thermal power, equal to one joule per second or 10 ergs per second (of a horsepower): for electric power it is equal to one volt-ampere.  POWER

Back to our analogy; electricity is the flow (like water) of electrons through a conductor like a wire. The rate at which electricity flows is measured as an electric current. The electric current is measured in amps. What makes the current flow? In our water analogy we could say a battery would be the pump that makes the water flow which creates pressure in the pipe. The pressure is the voltage. And as we said before the watts are the power the water could provide (like to a mill wheel). The watt is a measure of how much power is released!
