The synchronous speed of 4 pole, 50 Hz Induction Motor is:
- 750 RPM
- 1500 RPM
- 3000 RPM
- 6000 RPM
Correct answer: 2. 1500 RPM
Explanation: From formula of synchronous speed of induction motor:
ηsync= 120*f /P = 120 * 50/4 = 1500 RPM

I am interested in electrical engineering multiple choice questions.
I want to say please provide the numerical questions in electrical engineering subjects.
