A dynamometer wattmeter can be used for______________?
Correct answer: A. both D.C. and A.C.
- A. both D.C. and A.C.
- B. D.C. only
- C. A.C. only
- D. any of the above
Explanation
A dynamometer wattmeter uses the interaction of magnetic fields produced by its fixed and moving coils, a principle that works with either steady current or alternating current. It can therefore measure both D.C. and A.C. power.
