When a 1 kΩ load resistor is connected across the secondary winding of a transformer with a turns ratio of 2:1, the source "sees" a reflected load of .
A)2 kΩ
B)4 kΩ
C)500 Ω
D)1 kΩ

Question

Quizplus · Accepted Answer

The turns ratio of the transformer is 2:1, meaning the primary has twice as many turns as the secondary. The reflected load is calculated by multiplying the load resistance by the square of the turns ratio: (2^2) * 1 kΩ = 4 kΩ.
