Question

What determines the frequency of a.c. produced in a generator

Answer 1

we can determine the frequency of Ac produced in a generator by number of magnetic poles and rotational speed.Also Ac generator have a frequency of 60cycle per second

Answer 2

• The frequency of a.c. produced generator is determined by the number of poles and the speed of the rotor.
• While dealing with electricity,frequency is the interval at which the sine wave magnitude of the voltage and current alternate between positive and negative due to the reverse of current polarity because the conductors are passed by alternating north and south magnetic poles.
• In general ac generators have 50-60 cycles per second.
• The mathematical description for frequency is
• frequency = (speed [rpm] * number of poles ) / 120 [a constant for the conversion factor to correct for multiplying Cycles per Second, Poles per Cycle and revolutions per Minute}
