In part 1, we learned that electricity is quantified in two ways; voltatge and amperage, which describe force and quantity, respectively. However, in addition to those quanitfiers, there is one other characteristic of electricity that has to do with the motion of the current. Electricity comes in two forms of charge carrier movement; direct current and alternating current.

Let’s take a quick look at DC, and then we’ll examine AC.
