Q.

In a transformer, the exciting current will be in phase quadrature with the impressed voltage provided

  • AOnly the leakage impedance drop is ignored
  • BOnly the core loss is ignored
  • CBoth the leakage impedance drop and the core loss are ignored
  • DOnly the no load copper loss is ignored
Correct Answer : (C)

Both the leakage impedance drop and the core loss are ignored

Hints :
Previous

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

Next

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