DC voltage
Battery terminal measurement
DC voltage is electrical potential that flows in one constant direction, as opposed to alternating current (AC), which periodically reverses.
Batteries produce DC voltage; wall outlets supply AC.
The abbreviation stands for direct current.
The circuit requires 12 volts DC.
Most electronic devices convert AC power to DC voltage internally.
