Why we use 50 Hz Frequency?


Why should be the frequency is 50 hz only why not others like 45, 95 56 or anything , why should we maintain the frequency constant if so why it is only 50 ?


We can have the frequency at any frequency you like, but than you must also make your own motors, transformers or any other equipment you want to use.We maintain the frequency at 50hz or 60hz cos the world maintains a standard at 50 /60hz and the equipments are are made to operate at these frequency.
