Correct Answer : Option (D) : Mostly, the steady-state magnetizing current relying upon the initial state of the residual flux in the transformer core.
Explanation : When the transformer is in no-load condition, the secondary winding of the transformer has no load associated with it, and the transformer draws the zero current form the primary side of the winding.
Practically whenever the transformer is in no-load condition, a small amount of current is drawn form the primary side of the winding to set up the required magnetic flux in the core of the transformer.
