Chapter 1 is all about getting you introduced to basic concepts of electricity, current, voltage, and resistance.  At the end, we’ll bring it all together and introduce one of the most important, and probably one of the most simple concepts: Ohm’s Law.  These concepts that you may be familiar with, but laying the foundation is important; read these carefully.
