When a 1 $\mathrm { k } \Omega$ 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) 1 $\mathrm { k } \Omega$
B) 2 $\mathrm { k } \Omega$
C) 4 $\mathrm { k } \Omega$
D)  250$\Omega$

Quizplus · Accepted Answer

The reflected load is calculated by dividing the load resistance by the square of the turns ratio. Here, $ (1 \, \text{k}\Omega) / (2^2) = 250 \, \Omega $.
