$$\text { Figure } 14

Question

$$\text { Figure } 14 < 1$$
-In Figure 14-1, if the primary to secondary turns ratio is 9:1 and a 1 $\mathrm { k } \Omega$ load resistor is placed in the secondary, the reflected resistance seen by the primary equals_______
A) 111$\Omega$ 
B) 162$\mathrm { k } \Omega$ 
C) 81 $\mathrm { k } \Omega$ 
D) 1 $\mathrm { k } \Omega$

Quizplus · Accepted Answer

The reflected resistance can be calculated using the formula:
Reflected resistance = (turns ratio)^2 x load resistance
Substituting the given values, we get:
Reflected resistance = (9/1)^2 x 1000 Ω = 81,000 Ω or 81 kΩ.
Therefore, the correct answer is option C.
