What is DC current?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
DC (Direct Current) is electric current that flows continuously in one direction, from positive to negative terminal. The voltage and current magnitude remain constant over time. Batteries, solar cells, and DC power supplies produce direct current. DC is used in:
- Electronic devices (computers, phones, tablets)
- Battery-powered euipment
- Automotive electrical systems
- Many low-voltage applications
Unlike AC current, DC doesn't change direction, making it ideal for electronic circuits and devices reuiring stable, unidirectional power.
