Here’s the simple summary that describes what appliance techs need to know about current:
In the presence of voltage, electrons will travel on ALL valid paths in inverse proportion to the resistance in each path. Less resistance = higher current and vice versa. UNLESS there is a shunt or a short. If electrons have a path available to them with ZERO resistance, then they will choose that 100% of the time over any other paths with some amount of resistance.
The math bears this out, if you play around with it. (See Module 3, unit 5)
Does that help?
