**Circuit Failure Analysis Exercise**

**Objective:**  
Determine the output voltage for the circuit in Figure 2 for each of the following failure modes, and compare it to the correct output:

(a) R1 open  
(b) R2 open  
(c) C open  
(d) C shorted  

**Circuit Description:**  
- **Figure 2** depicts a simple RC circuit consisting of:
  - A voltage source \( V_s = 1 \, \text{V} \) with a frequency \( f = 10 \, \text{Hz} \).
  - Resistor \( R_1 \) with a resistance of \( 10 \, \text{k}\Omega \).
  - Resistor \( R_2 \) with a resistance of \( 10 \, \text{k}\Omega \) in parallel with a capacitor.
  - A capacitor \( C \) with capacitance \( 4.7 \, \mu\text{F} \).
  - The output voltage \( V_{\text{out}} \) is measured across the parallel combination of \( R_2 \) and \( C \).

**Failure Modes Explained:**

- **(a) R1 open:** This failure mode implies that there is a break in the circuit where \( R_1 \) is located, effectively removing it from the circuit.

- **(b) R2 open:** This indicates a break across \( R_2 \), meaning the resistor is not contributing to the circuit anymore, affecting the parallel branch with the capacitor.

- **(c) C open:** The capacitor is disconnected, which means it is not holding any charge or affecting the impedance of the parallel branch. 

- **(d) C shorted:** This situation means the capacitor is providing a low-resistance path (like a wire), effectively bypassing \( R_2 \) in the parallel branch.

**Note:**  
By analyzing these conditions, you'll understand how each component affects the circuit's output voltage, which is crucial for troubleshooting and designing reliable electronic systems.
