When a 1 kΩ load resistor is connected across the secondary winding of a transformer with a turns ratio of 1:2, the source "sees" a reflected load of .
A)250 Ω
B)4 kΩ
C)1 kΩ
D)2 kΩ

Question

Quizplus · Accepted Answer

The reflected load is equal to the square of the turns ratio times the load resistance. In this case, the turns ratio is 1:2, so the reflected load is (2)^2 * 1 kΩ = 4 kΩ.
