Answer:A
Under which of the following conditions hunting of synchronous motor is likely to occur ?
A. Periodic variation of load B. Over-excitation C. Over-loading for long periods D. Small and constant load
Explanation: Hunting is the phenomenon that occurs in synchronous motors due to varying load or supply frequency.
