Question

$$\text { Figure } 13 < 1$$
-If frequency increases in Figure 13-1, the impedance ________ and the current ________.
A)decreases, decreases 
B)increases, increases 
C)decreases, increases 
D)increases, decreases

Quizplus · Accepted Answer

In Figure 13-1, the impedance is represented by the vertical distance between the two parallel lines, and as the frequency increases, this impedance increases. According to Ohm's Law, I = V/Z, where I is the current, V is the voltage, and Z is the impedance. Therefore, if the impedance increases and the voltage remains constant, the current must decrease. Therefore, the correct answer is that the impedance increases and the current decreases. This is represented by choice D.
