Electro-mechanical voltage regulators are generally used in___________?
Correct answer: B. generators
- A. reactors
- B. generators
- C. transformers
- D. all of the above
Explanation
Electromechanical voltage regulators, such as regulators used with alternators, adjust generator excitation to maintain terminal voltage. They are therefore generally associated with generators rather than reactors or ordinary transformers.
