Question

$$\text { Figure } 19 < 3$$
-If  R=1.2  $\mathrm { k } \Omega$ and  C=0.005  $\mu \mathrm { F }$ in Figure 19-3, the $\mathrm { fCO }$ equals________
A) 65 Hz 
B) 650 Hz 
C) 26.5 kHz 
D) 2.65 kHz

Quizplus · Accepted Answer

The resonant frequency is given by:$$f_0 = \frac{1}{2\pi RC}$$Substituting the given values:$$f_0 = \frac{1}{2\pi (1.2 	ext{ k}\Omega)(0.005 \mu 	ext{F})}$$$$f_0 = 26.5 	ext{ kHz}$$
