In an electrical circuit, voltage equals pressure. Low pressure = lower voltage and high pressure = higher voltage. A good analogy to use to try to wrap your head around things is water. Voltage is the same as how hard the water is coming out of the water hose. It can also be called a difference in potential. So, when measuring voltage with your meter you may be able to read 120v or 240v in residential applications or up to 480v in commercial or industrial applications. In electrical calculations, Voltage is written as V or E. The next term we should cover is Amperage. While voltage is pressure, amperage is current flow. Again, this term is directly proportional. Lower amperage = lower current flow and higher amperage = higher current flow. Going back to our water analogy, amperage could be thought of as how much water is flowing, not necessarily how HARD. In electrical terminology, amperage is written as A or I. Resistance is the next term to discuss. Resistance is opposition to current flow. Everything electrically that we use has some form of resistance in it. From a light bulb to a vacuum to a television and so on. The interesting thing about resistance is that it slows down current flow to a rate that is usable. Without some form of resistance, the current flow would be so high that we would short our circuit out (this is what happens when we take our load out of a circuit and hook the hot wire straight up to our neutral. BANG!) in electrical calculations resistance is written as R or the omega symbol and is measured in Ohms. Lastly, we will talk about Watts. Wattage is how much power is being consumed/expended. The lower the wattage the smaller the load is. Take a light bulb for instance. A 60w lamp is not as bright as a 100w lamp. But it’s not just confined to lamps. Every piece of equipment has a wattage rating; toasters, vacuums, tv’s etc. These simple terms can also be used in conjunction with one another to find one that is missing. Basic Ohm’s law. So, for example, if you knew what voltage your equipment was operating at and how many amps it drew, you could use the Ohms law formula of voltage x amperage = wattage.
