Direct Current - GCSE Physics Definition

Reviewed by: Philippa Platt

Published

Direct Current (DC) is a type of electrical current where the flow of electric charge is unidirectional, meaning it moves in a single, constant direction.

In GCSE Physics, students learn that DC is typically produced by sources such as batteries and solar cells. Unlike alternating current (AC), which regularly changes direction, DC maintains a steady flow, which makes it ideal for devices that require a constant voltage.

Understanding DC is crucial for exploring how electricity powers various electronic gadgets and circuits commonly used in everyday life.
