I think of electricity in terms of a garden hose. Pressure=voltage, or the potential to do mechanical work. Resistance can be varied by twisting the nozzle to a new diameter. Current is how fast the water molecules or electrons are flowing. Less resistance leads to greater flow at lower pressure. This is for the conventional current view of electricity that I chose to relate to. Eric’s description recently is based on the flow of holes, which would be air bubbles moving against the flow.
I couldn’t phrase your request right for Gistweb dot com to locate anything to summarize, but perhaps one of y’all can, or give me some search/ keyword strings to try tonight.
