What is the output frequency of an alternator that contains six poles per phase and is turning at a speed of 1000 RPM?
A) 0.72 Hz
B) 7.2 Hz
C) 50 Hz
D) 20,000 Hz

Question

Quizplus · Accepted Answer

The formula to calculate the output frequency of an alternator is:

Output Frequency = (Number of Poles × Rotational Speed) ÷ 120

Substituting the values given in the question:

Output Frequency = (6 × 1000) ÷ 120
Output Frequency = 50 Hz

Therefore, the output frequency of the alternator turning at a speed of 1000 RPM with six poles per phase is 50 Hz.
