Ok, let's get to the meat of the topic. First I would like to help you understand a couple of concepts first. AC or alternating current is electricity that travels in two directions, backwards and forwards. Our goal is to convert normal AC electricity (usually found in the receptacle of the house) to DC (direct current). Direct current, as its name implies, is current running in only one direction at a mostly constant voltage (depending on how well the circuit is built, and with what components).
