Course Description

Direct current, commonly referred to as DC, is a form of electrical current that flows consistently in a single direction. This unidirectional flow is a distinguishing feature compared to alternating current, or AC, where the current reverses direction periodically. DC is commonly generated by batteries, solar cells, and DC power supplies. The magnitude of DC remains steady over time, which makes it ideal for devices requiring stable voltage and predictable operation. In engineering applications, DC forms the backbone of most low-voltage electronic circuits, such as those found in laptops, mobile phones, and automotive electronics.
