Measurement of power and potential. Literally. Amp is the current before you ask. Those are the units.
One thing is for certain: the more profoundly baffled you have been in your life, the more open your mind becomes to new ideas.
-Neil deGrasse Tyson
Let's think the unthinkable, let's do the undoable. Let us prepare to grapple with the ineffable itself, and see if we may not eff it after all.

Watt: It's the SI unit for power, or energy transferred per unit time. If you're using a 50W lightbulb, it means 50 joules of energy per second is consumed by the circuitry inside it.
Volt: It's the SI unit for electric potential, or the amount of energy that can be potentially transferred per unit charge by a charged particle. In your field you're usually interested in the potential difference between two points in a circuit, though. This is the change in potential for a 1 coulomb charge as it passes from the first point and to the second. So if you have a 5V potential loss between point A and B in a circuit, it means the electrons at point A have 5 joules of energy more per charge than the electrons in point B.
