Electrical Units 101

Electrical Units provides a foundational overview of electricity, including fundamental measures and terminology used to discuss electricity. Electricity is the flow of electrons, which are negatively charged particles. The amount of valence electrons in an atom determines how well it allows electricity to flow. There are two types of electricity, alternating current and direct current, but both flow from negative to positive. Current is measured by certain terms, including amperage, voltage, resistance, and wattage. Ohm’s Law and Watt’s Law describe the relationships between these values in a circuit. When working with electrical systems, knowing how electricity flows and what different terms mean is very important. After taking this class, users should be familiar with the fundamentals of electricity and the vocabulary used to describe it. This enables users to build an understanding of more advanced electrical concepts and discuss them with the correct terminology.
