Study Notes
DC Generators
- DC generators produce direct current (DC) electricity.
- DC generators utilize a commutator to transform alternating current (AC) into direct current.
- The commutator is a device that reverses the current direction in the coil windings.
- AC generators are more prevalent than DC generators.
