Answer / arul
I will explain with one example:-
if one textile company is there, some motor using for dress
making purpose. if frequency is fixed (50 hz) in this
condition we get normal dress (threads are correctly
matching). if variable frequency is there in this
condition, motor speed will change, we see in order
matching of thread in this dress.
so we use fixed frequency.

Answer / dileep
freauency will help to design the electrical appliances like mot ors
,genafators etc & performance is also depends upon the frequ.if we
change the frequency speed,flickering of light also changes
2).in the genaration view if frequency knows then we know dat how
