Question

The circuit shown in Figure P5.37 is a second-order circuit because it has two reactive components ( L and $C$ ). A complete solution will not be attempted. However, determine: a. The behavior of the voltage frequency response at extremely high and low frequencies. b. The output voltage $\mathbf{V}_o$ if the input voltage has a frequency where: $$ \begin{array}{ll} \mathbf{V}_i=7.07 \angle \frac{\pi}{4} \mathbf{v} \quad R_1=2.2 \mathrm{k} \Omega \\ R_2=3.8 \mathrm{k} \Omega & X_c=5 \mathrm{k} \Omega \quad X_L=1.25 \mathrm{k} \Omega \end{array} $$ c. The output voltage if the frequency of the input voltage doubles so that $$x_C=2.5 \mathrm{k} \Omega \quad x_L=2.5 \mathrm{k} \Omega$$ d. The output voltage if the frequency of the input voltage again doubles so that $$X_c=1.25 \mathrm{k} \Omega \quad X_L=5 \mathrm{k} \Omega$$ (FIGURE CAN'T COPY) Figure P5.37

calc-the-l-r-c-series-figure-p3166-circuit-shown-in-fig-mathbfp-3-1-6-6-has-an-ac-voltage-source-v_t

CALC The $L-R-C$ series Figure P31.66 circuit shown in Fig. $\mathbf{P 3 1 . 6 6}$ has an ac voltage source $v_{\text {in }}(t)=V_{\text {in }} \cos (\omega t),$ where $V_{\text {in }}$ is the input voltage amplitude and $\omega$ is its angular frequency. The values of the resistance, inductance, and capacitance of the components are $R, L,$ and $C$. The capacitance is variable. The output voltage is $v_{\text {out }}(t)=V_{\text {out }} \cos (\omega t+\theta)$. (a) What is the output voltage amplitude $V_{\text {out }} ?$ (b) What is the phase angle $\theta$ of the output voltage? (c) What is the value of $\theta$ at resonance? (d) If $R=100 \Omega, L=1.00 \mu \mathrm{H},$ and $V_{\mathrm{in}}=10.0 \mathrm{~V}$ what value of $C$ would result in a resonance frequency of $100 \mathrm{kHz}$ ? (e) In that case what would be the output voltage amplitude at resonance?

00:02 So for part a, we want v out.
00:06 So that would be v out is equal to vn divided by the square root of rwc squared plus w squared lc minus 1 squared.
00:26 For part b, we want the phase angle for v out, and the output voltage is across the capacitor.
00:33 So the phase angle is the same as for the capacitor.
00:37 So minus pi divided by 2 to where that is equal to arc tangent of wl minus 1 divided by wc over r is equal to arc tangent w squared lc minus 1 over wrc...
