Question

The power factor of a universal motor is:

• A. Unity at no load
• B. 0.7 to 0.8 at full load
• C. 0.7 to 0.8 at no load
• D. Unity at full load

Hint:

Universal motors tend to have lower power factors, particularly under no-load conditions, due to the characteristics of the motor.

Answer 1

The Correct Option is B

A universal motor typically has a power factor in the range of 0.7 to 0.8 when it is operating under full load conditions. The power factor is lower at no load.
