Question

Answer each part, some may have multiple answers.

Which statement is correct about an ideal two-winding transformer?
Select all that apply:
A. There is no phase shift existing between the voltage phasors on the two sides
B. There is no phase shift existing between the current phasors on the two sides
C. There is a 90∘ phase-shift between the voltage and current phasors on each side
D. There is no phase-shift between the voltage and current phasors on each side

Answer 1

An ideal two-winding transformer has no phase shift between voltage and current phasors on each side.

Step-by-step explanation:

An ideal two-winding transformer is a device that transfers electrical energy between two circuits through electromagnetic induction. The primary winding, with Np turns, is connected to the primary voltage, while the secondary winding, with Ng turns, is connected to the load resistor. The transformer equation states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of turns in their coils.

Therefore, for an ideal two-winding transformer:

1. Statement A: There is no phase shift existing between the voltage phasors on the two sides.
2. Statement B: There is no phase shift existing between the current phasors on the two sides.
3. Statement D: There is no phase shift between the voltage and current phasors on each side.
