Question
Assuming an ideal transformer, the Thevenin’s equivalent voltage and impedance as seen from the terminals x and y for the circuit in figure are

Correct answer
(A) 2 sin(ω t), 4 Ω
Solution
For an ideal transformer with turns ratio :
1.Thevenin Voltage (): The open-circuit voltage at the secondary terminals x-y is the primary voltage multiplied by the turns ratio.
2.Thevenin Impedance (): The impedance seen from the secondary is the primary impedance multiplied by the square of the turns ratio.
Thus, the equivalent is and .Continue learning with Success Tracker
