Reported Question / Answer
Core Loss= Eddy+ Hysteresis Notations: f-frequency,V-voltage, Ke,Kh-constant, B-flux Eddy = Ke*(f^2)*(B^2) = Ke*(f^2)*(V/f)^2 = Ke* V^2 = constant Hysteresis = Kh*(f)*(B^1.6) (1.6-for stainless steel core) = Kh*(f)*(V/f)^1.6 = Kh*(V^1.6)/(f^0.6) =constant/(f^0.6) If f increases, hysteresis decreases and eddy is constant. Therefore, core loss decreases.
correct answer is A
Answer is 1. Since it is operating in constant voltage the core loss decrease
