The reasons for power supply frequency in India to be 50 Hz
and in US to be 60 HZ are:
1.ENVIRONMENTAL FACTORS :::::The average annual temperature
of India is greater than US
2.POWER GENERATION REASONS :To generate power of that
frequency it costs alot and the size of the alternator is
huge and it costs an incredible amount which we cant afford
3.EDDY CURRENT LOSSES :As frequency increases eddy current
and hysteriss losses increasesand hence power loss also
increases.
