Voltage is potential difference, anon. Which is the difference in electric potential between 2 points. Which issss the amount of energy unit charge would have if located in space, and is equal to work done taking a positive test charge from infinite (0 potential) to that point (x potential).

Ampage is just current. Q = IT. It's the rate of flow of charge in a circuit.

Think of a wire as a water pipe.

The speed at which the water flows is the amperage, the pressure of the water is the voltage, and the resistance of the water to flowing is the… well, resistance. If you have a sudden bottleneck in the pipe, analogous to a resistor, the water suddenly becomes a lot more resistant and thus the pressure shoots up, unless you slow the water down.

Note that it is the momentum of the water particles that is important and not the water particles themselves in a pipe (for this analogy.) It would be perfectly possible to have a pipe of water where the water moves back and forth and have a "capacitor" (a small skin of rubber like a drum head) blocking the pipe and have another section filled with fluid and transmit the wave through the pipes.

>capacitor

and how would you model an inductor? a turbine?
