why we maintain 50hz ,220volts,20Amp,ratings fixed every
where in india,,electricity
Answer Posted / logan
in india we've got the more resources for producing
electricity. and also if we use the 50hz,220v the losses
will be less and we can save more power.
but in case of USA, they're using 60hz frequency as the
resources are very less for power production. and they cant
mind for the losses.
