Answer / ramesh kumar k
Rahul & Balaji both are right...
As the HYSTERISIS and EDDYCURRENT Losses are directly
proportional to the Frequency, definitely they will increase
and also the reactance also increases with increase in
frequency the reactance drops are also increased...

Answer / balaji
The inductive reactance depends upon the frequency.If
frequency inreases XL will increase.Losses will also
increase.
