Introduction to Circuits

“Introduction to Circuits” provides a foundational overview of electrical circuitry. Whether wired in series, parallel, or a combination of the two, all circuits consist of a source, path, control, and load. Each of these components serves a purpose, and many circuits have extra components to prevent safety hazards and damage. Visual representations of circuits, such as schematic diagrams, use symbols of these components to illustrate the circuit’s layout. This method makes it easier to understand circuits and the rules that describe how they function, such as Kirchhoff’s Laws. Understanding how circuits work is essential when working with electricity. This includes being familiar with circuit components, circuit diagrams, and the rules that govern circuits, which serves as the basis for understanding advanced electrical topics. Without the foundational information presented in this class, users would not be prepared to study more complex aspects of electrical systems.
