If given alternating speed is 25r/s and the alternator has 6 poles, determine the frequency

To determine the frequency, we need to recall the formula:

Frequency = Alternating Speed / Number of Poles

Plugging in the given values:
Alternating Speed = 25 r/s
Number of Poles = 6

Frequency = 25 r/s / 6

Therefore, the frequency of the alternator is approximately 4.17 r/s.
