A power factor meter has________________?
Correct answer: A. one current circuit and two pressure circuits
- A. one current circuit and two pressure circuits
- B. one current circuit and one pressure circuit
- C. two current circuits and one pres¬sure circuit
- D. none of the above
Explanation
A power-factor meter uses one current circuit and two pressure circuits to obtain the phase relationship between current and voltage. The two pressure circuits produce the necessary phase-sensitive torque.
