WebMar 24, 2024 · Download Solution PDF. The correct answer is option 4. Concept: In a DC generator, the commutator also known as a split ring facilitates the collection of current from the armature conductors and converts the alternating emf induced (AC) in the armature conductors to unidirectional emf (DC) in the external load circuit. WebDC generators are the devices which convert mechanical energy into electrical energy and provide output in the form of direct current. DC generators operate on the principle of electromagnetic induction. The voltage and current in a DC generator are unidirectional. The DC generators have an efficiency rate of 85-95%.
