Answer / srikanth

if frequency is increases current decreases(due to inversly
proposational) current deceases area of conductor size is
decreases(directly propsational) size decreases then power
loss consuption will be reduced..

Answer / chandru

When we increase the level of frequency, level of power
losses will automatically reduce.As we are aware of
transformer emf equation, E=4.44fNAB.
f=frequency,A=area of cross-section,B=magnetic flux density
when we increase the frequency, by having E&B as
constant,area of cross-section will reduce.So,the size of
transformer can be reduced with higher frequency

Answer / c_elavarasi@yahoo.com

frequency is inversely propotional to the reactance,so if
the frequency increases,reactance decreases thereby current
gets increased.so if the resistance is constant,voltage
increases so that the windings cant be able to withstand
the increased voltage and also if the current increases
I^2R losses will increase.

Answer / anil

50 HZ is uswed in india and also majority in other world.
some of countries uses 60 HZ as UK . The frequency is
inversly proportional to current ,so when drops current
increases or vise versa.the change of frequency is uses in
VFD to change speed .
