That's a good analogy, but not 100% accurate.

Here's a better one.

Think of the electrons as a bunch of tiny workmen moving around a track (the circuit). The strength of the workmen is determined by their voltage. The current is the number of workmen that can work per second. The amount of work they need to do is the resistance.

So if the voltage is high (stong guys) you dont need as many of them (current) to get the same work doen. Alternitively if if they are weak you require more of them to do as much work.

If you reduce the workload (ie resistance) but keep up the strength (voltage) each guy finishes his work quicker and more of them can move around the track (higher current).
