can somebody give an analogy of what an ampere is?
To a first approximation, amps is the number of electrons passing a given point in a second (divided by about 6 x 10^18, but it's proportional - twice as many electrons, twice as many amps). I say to a first approximation, since for p-type semiconductors the current is produced by moving vacancies in the electron cloud, and no single electron can be singled out for counting.

Watts is how much work you do in a unit time interval in pushing those electrons, and for electronic systems it's volts times amps.

Think of electricity in a wire as water in a pipe. Amps is the flow rate, volts is the pressure drop from one end of the pipe to the other, and watts is the power needed to move the water - or the power produced by moving the water as in a hydroelectric generator.
