**Circuit Description and Analysis**
In this section, we will analyze the circuit depicted in Figure 3. The circuit consists of several resistors, a capacitor, and a voltage source. Let’s examine each component and their configuration:
### Circuit Diagram Description
- **Components:**
- A 12V voltage source
- Resistors: 12Ω, 20Ω, 80Ω, 5Ω, and 60Ω
- A 50μF capacitor
- A switch that can be opened or closed
- **Configuration:**
- The 12Ω and 20Ω resistors are connected in parallel.
- The resulting parallel combination is connected in series with an 80Ω resistor.
- This series combination is then connected in parallel with a 50μF capacitor.
- Finally, this is connected in series with a 5Ω resistor and the 12V voltage source.
### Analysis Tasks
1. **Find the Initial Voltage (v0):**
- Determine the initial voltage on the capacitor just before the switch is flipped.
2. **Find an Expression (v(t)):**
- Develop an expression that describes the voltage across the 20Ω resistor after the switch has been altered, allowing the circuit to reach a new state.
3. **Use Circuit-Specific Equations:**
- Apply circuit-specific equations to get a value you can verify. Use this as a problem-solving strategy for various numerical exercises.
Remember, solving these steps will help you understand how circuits respond to changes and provide insight into their dynamic behavior.
