Why, Alternating Current and Direct Current, of course! Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.
The transformer rectifier units in a volts direct current (VDC) power system convert three-phase 115 volts alternating current (VAC) into: b. 26 to 31 VDC. In the direct current (DC) power supply system, the delta-wound secondaries of the internal transformer rectifier (TR) unit are used to provide a more stable: c. Current output. In the direct current (DC) power supply system, the reverse current relays (RCR) deenergize when the potential at the:
