### Problem Statement
2) In the following circuit, find \( v_o(t) \).
- **Consider:**
- \( R_1 = 10 \, \Omega \)
- \( R_2 = 2 \, \Omega \)
- \( C = 0.2 \, F \)
- \( v_i(t) = 2 \cos(5t) \) volts
### Diagram Explanation
The diagram is a non-inverting amplifier circuit. It includes:
- A resistor \( R_1 \) connected in series with the positive input of the operational amplifier.
- A parallel combination of a resistor \( R_2 \) and a capacitor \( C \) connected to the negative input.
- \( V_i \) is the input voltage, and \( V_o \) is the output voltage.
### Solution
- **Impedance of the Capacitor:**
\[
Z_c = -j \, 1 \, \Omega
\]
- **Non-Inverting Amplifier Equation:**
\[
V_o = V_i \left(1 + \frac{Z_2}{R_1}\right)
\]
- **Parallel Impedance:**
\[
Z_2 = R_2 \parallel Z_c
\]
- **Output Voltage:**
\[
V_o = 2.1 \, \angle \, -4.4^\circ \, \text{volts}
\]
- **Output Voltage as a Function of Time:**
\[
v_o(t) = 2.1 \cos(5t - 4.4^\circ) \, \text{volts}
\]
