Question 511Electricity & Electronics - QMED

The correct answer is C) They both internally generate alternating current voltages. Both AC (alternating current) and DC (direct current) generators internally generate alternating current voltages. The main difference is that AC generators directly deliver this alternating current, while DC generators use a commutator to convert the AC to direct current before delivery. The other options are incorrect because: A) Rectifying the voltage is a function of DC generators, not a similarity between AC and DC generators. B) Supplying three-phase power is a feature of some AC generators, but not a universal similarity between AC and DC generators. D) Operating at 60 cycles is a specification for the electrical system, not a similarity between the generator types.
