Electrical – Operations
Understanding some of the fundamental concepts of electrical circuits is vital to being able to operate and troubleshoot electrical systems. This course covers some basic electrical terminology, the sources of electricity, circuit overcurrent protection, and methods for measuring electricity. Electric current is driven by an electric potential difference, or voltage. Voltage sources include generators, batteries, and photovoltaic sources. Conductors are materials which allow the free flow of electricity and connect all other components in an electrical circuit. Insulators are materials which block the flow of electricity. The flow of electricity within a circuit needs to be properly contained. There is a need for protection from the dangers of overcurrent conditions in circuits. This protection is provided by fuses and circuit breakers. Electrical systems should also be grounded and bonded. A multimeter is a device that can be used to measure voltage, current, and resistance. Permanently-mounted power meters measure the amount of power entering a building and how it is consumed throughout the building.
