Time for part 2 of this thing: Current. I is the second term in V=IR (obviously). It is also the one thing about electricity that scares the crap out of me. When it comes to electrical shocks, the current is what makes them deadly.
Current describes the rate of flow on the electrical charge. It is the change in coulombs (electrical charge)/change in time. Going back the the hydraulic analogy, current is the flow rate of the water. Current is measured in amperes (A).
This is a quick post. Next week will be R (resistance), and I will also bring everything together for an explanation of Ohms Law.
