Ferrite cores are employed in high frequency transformer because it has

  • ALow resistance
  • BHigh resistance
  • CLow permeability
  • DHigh hysteresis loss
Correct Answer : (B)

High resistance

Hints :

If a sinusoidal voltage source is connected to a power transformer, it's no load current would be


On no load phasor diagram of transformer, the core loss component of the current remains in phase with
