Question

$$\text { Figure } 19 < 3$$ -If R=22 $\mathrm { k } \Omega$ and C=0.05 $\mu \mathrm { F }$ in Figure 19-3, f_CO equals________ A) 145 Hz B) 4.8 Hz C) 48 Hz D) 1.45 kHz

Quizplus · Accepted Answer

From the formula given in the circuit, we have: $$f_{_CO} = \frac{1}{2\pi R C}$$ Substituting R = 22 kΩ and C = 0.05 μF, we get: $$f_{_CO} = \frac{1}{2\pi \cdot 22\cdot 10^3 \cdot 0.05 \cdot 10^{-6}} = 145 ext{ Hz}$$ Therefore, the answer is A.
