Q.

The Transformer exciting current has two components, magnetizing component and core-loss component. Neglecting Impedance drop

• ABoth of them are in phase with the supply voltage
• BThe former lags the supply voltage by 90 degree while the later is in phase with supply voltage
• CBoth of the lag the supply voltage by 90 degree
• DThe former is in phase with supply voltage while the later lags the supply voltage by 90 degree
