Question

Good day, please solve problem 8.45 showing all steps. This problem is just for practice and not for a grade. I have also attached the correct answer for the problem in the images below, as well as the problem statement. Thank you so much for your help. 

The image appears to display a list of problems or exercises from a textbook, potentially related to electrical engineering. Below is a transcription of the listed text from the image: 8.31 (a) 1.88 - j0.22 Ω, (b) 1 Ω, (c) 0.4 + j1.2 Ω 8.34 2.77 cos(√3t - 60°) A 8.35 6√2/165° V, 0.5 - j9.5 Ω 8.37 cos(2t - 90°) = sin 2t V 8.39 6.8∠30° A, 6.8∠-90° A 8.41 (a) 5.88 cos(2t + 78.7°) V, (b) 1.15 - j0.23 Ω 8.43 (a) 6.91 - j0.30 Ω, (b) 3.20 - j0.40 Ω 8.45 (a) 0.219 cos(5t - 146.9°) V, (b) 0.5 - j0.2 Ω 8.47 2√2 cos(4t + 45°) V --- This list includes expressions involving phasors, impedance, and sinusoidal functions, which are common in alternating current (AC) circuit analysis. Each line provides a different mathematical expression to analyze or solve. The notations involve angles, complex numbers, and standard AC signals.

## Textbook Problem Descriptions and Circuit Analysis ### Figure P8.44 Description: This figure illustrates an op-amp circuit. The circuit has the following components: - An input voltage source \( v_s = 6 \sin 2t \, \text{V} \). - A resistor of \(2 \, \Omega\) connected at the inverting input of the op-amp. - A parallel connection of the resistor and a capacitor of \( \frac{1}{4} \, \text{F} \). - A \(1 \, \Omega\) resistor connected to the ground. - The output voltage is denoted as \( v_o \). ### Exercise 8.45: - **Task**: For the op-amp circuit shown in Fig. P8.44, calculate: - (a) The output voltage \( v_o(t) \). - (b) The impedance seen by the voltage source. ### Figure P8.45 Description: This figure depicts another op-amp circuit. The key elements are: - An input voltage source \( v_s = 3 \cos 5t \, \text{V} \). - A \( \frac{1}{2} \, \Omega\) resistor in series with a \(1 \, \Omega\) resistor. - Two \(1 \, \text{F}\) capacitors, one connected in series and the other to the ground. - The output of the op-amp is labeled as \( v_o \). ### Exercise 8.48: - **Task**: For the series RC circuit shown in Fig. 8.33(a), adjust the capacitor value to \(1 \, \text{F}\) and determine \( v_o(t) \) given: \[ v_s(t) = \frac{1}{\pi} + \frac{1}{2} \sin \pi t - \frac{2}{3\pi} \cos 2\pi t \, \text{V} \]
