The speed/load characteristics of a universal motor is same as that of_____________?
Correct answer: C. D.C. series motor
- A. A.C. motor
- B. D.C. shunt motor
- C. D.C. series motor
- D. none of the above
Explanation
A universal motor is a series motor that can operate on either AC or DC, so its speed-load characteristic resembles that of a DC series motor. Its speed rises sharply as load decreases, making no-load operation dangerous.
