why AC voltage source are generate as 50 Hz ?
Answers were Sorted based on User's Feedback
Answer / skeeter
Synchronous sources operate according to the equation:
(Hz) = (Poles)*(RPM)/120.
Generation can occur at any frequency that meets this
condition. Every electrical distribution network has its
preferred freqeuncy; North America is predominantly 60 Hz,
while Europe and Asia tend to favor 50 Hz. However, several
other frequencies also exist - ranging from 25 Hz to
several megahertz.

5o Hz is the standard frequency in india, technically the
frequcy produced by the Ac genrater depends on F= Number of
poles*Speed of generator/120 which is equal to 50 HZ for a
4pole 1500 Rpm and running speed of generator is 1500 RPM

INDIAN STANDED ALL THE LOAD IN 50HZ BASED ON DESING OF
MANUFA... TO ALTERNATOR Ns*p/120 s0 positive cycle &-ve cycle
in 50hz where Ns=1500rpm

This is standared in india AC power is produced at 50 hz
frequency out of india it's 80 hz. Due to this sign wave of
current and volatage complete grah.

Active power= VI COS FI But incase of leading power factor ( more than unity), may we use other formula ? because the cos fi (value of cos thita) should not be grater than one.
