DC circuit
One-way electrical loop
A DC circuit is an electrical circuit powered by direct current, where electricity flows in one direction only—as from a battery.
This contrasts with AC circuits, where current alternates direction.
DC circuits are fundamental in electronics education and power most portable devices: The student built a simple DC circuit with a battery, resistor, and LED.
