Voltage is like the pressure of the water in your garden hose.

The resistance in a circuit has the same effect as opening and closing the nozzle (more or less resistance)

Amperage is how much water comes out the end.

Watts, or work, is how much water goes into the bucket.

This is what one instructor said to me that finally made it click, many, many years ago.

If you are still not sure, read it again slowly.

Ohms Law: V(voltage) = I(current in Amps) x R(resistance)

...or after some algebraic manipulation (I'll spare you the mathematical Kung-Fu), the derived equation for Power:

P(Power in Watts) = V(voltage) x I(current in Amps)
