Ok /sci/ - i'm not an engineer, i'm not very smart with electronincs, but I recall a kind of comparison between voltage and amperage and resistance.

it was something about water. You have a battery/bottle - the size of the hole in the bottle is the voltage, the amperage is the pressure of the water coming out (or is it the other way around), and resistance is adding a filter/sponge to plug the hole.

this make sense?

Voltage is pressure, amperage is water flow, resistance is size of the opening.

Nope, you fucked up the analogy!

are you sure, you sure sound like a faggot (engineer)

basically. The only difference is that with pressure you can use one probe to measure pressure, but with voltage you have to compare "pressure" between two points.
