3. Basic Current Laws
There are a few basic current laws that everyone should know. The first one may be intuitive based on the fundamental definition of current. Remember that current is the flow of electrons.
3.1. Flows in a Loop
If current is the flow of electrons, then current must flow in a closed loop. If current (electrons) flows out of some source (a battery, for example), then current (electrons) must flow back to that source. Consider the implications if this were not so. If electrons could flow out of a battery and not return, where would they go? If electrons can leave one place (and not return), one of two conditions must be true: ...
