Please do and throw in the Watt please.

BTW Your definition is more logical then what I learned. If you would like

please comment on voltage being defined as the potential difference between

two points period.

Voltage is defined as the potential difference between two points. The

"period" is a punctuation mark.

Potential is like pressure.

When you compress a spring, you give it potential energy, which it

stores up in the form of the stress on the spring itself. When you

release the spring, that energy is released as "kinetic energy", but

that's another topic.

The point is, that "potential" corresponds to "pressure." It's

something like water flowing downhill, where the "potential energy" is

represented by the height of the water column - actually, the height is

the voltage - the current, obviously, is the flow, and the power is

the pressure times the flow.

Now, if you just let the water fall, then the analogy to an electronic

circuit kind of breaks down, except that a waterfall might be kind of

conceptually like an arc.

But if it falls through a waterwheel, then you can extract energy from

it. The amount of energy you can extract at any given moment can be

expressed as (or derived from?) the flow rate multiplied by the pressure

difference. No, wait - rate - that's the rate at which you're extracting

energy. Energy and work are almost interchangeable - I had a physics

teacher who said, "Energy is the capacity to do work." Work, of course, is

force times distance. And power is the rate of doing work.

Hope This Helps!
