Direct Current (DC) circuits are foundational in electrical engineering, powering
a wide range of devices from small electronic gadgets to electric vehicles.
Unlike Alternating Current (AC) circuits, where current alternates direction, DC
circuits have a steady current that flows in a single direction, usually from a
positive to a negative terminal. Understanding the fundamentals of DC circuits
is essential for working with electronics, as they offer insight into voltage,
current, resistance, and power—core concepts in electrical studies.
