direct currents
One-way electrical flows
Direct currents are electrical currents that flow in one direction only, as opposed to alternating currents, which periodically reverse.
Batteries produce direct current; wall outlets typically supply alternating current.
The abbreviation DC appears in contexts from electronics to comic books: DC power, DC Comics.
The device runs on direct current.
