Question

**Transcription and Explanation for Educational Purposes:**

**Circuit Description:**

The circuit diagram shown features a combination of capacitors, resistors, and a current source. Here's a detailed breakdown:

1. **Current Source:**
- A constant current source of 1 mA is connected in series with a 20 kΩ resistor.

2. **Resistor:**
- The first resistor has a resistance of 20 kΩ.

3. **Capacitors:**
- There are two capacitors in parallel: a 150 µF capacitor and a 50 µF capacitor.

4. **Switches and Time Notations:**
- The circuit includes a switch, which initially (at \( t = 0 \)) connects the current source and the 20 kΩ resistor with the capacitors.
- A second switch position is shown for \( t \geq 2 \) seconds, which redirects the circuit path to add an additional 20 kΩ resistor in parallel with the 50 µF capacitor.

5. **Output Current and Voltage:**
- The diagram specifies two quantities to be plotted as functions of time:
- \( i_0(t) \): The current through the 50 µF capacitor.
- \( v_0(t) \): The voltage across the 50 µF capacitor.

**Analysis Objective:**

The goal is to determine the behavior of the current \( i_0(t) \) and the voltage \( v_0(t) \) in response to the initial conditions and the change in circuit configuration at \( t = 2 \) seconds. This involves solving the circuit equations for these parameters over time.

**Educational Analysis:**

To analyze the circuit:
- Use Kirchhoff's laws and capacitor charge-discharge equations.
- Find the time constants and steady-state responses.
- For \( t < 2 \) seconds, consider the initial RC circuit consisting of the 150 µF and 50 µF capacitors in parallel with the resistor.
- For \( t \geq 2 \) seconds, analyze the modified circuit configuration when the switch changes position.

**Graphical Representation:**

The graphs of \( i_0(t) \) and \( v_0(t) \) will typically show exponential charge and discharge curves representing the dynamic response of the capacitors to the changes in the circuit configuration over time.
