Question

Capacitor C is initially uncharged at t=0 (when switch S is toggled from open to closed).  What is the change in the voltage drop V2 across resistor R2 from t=0 to t = ∞ (meaning a large number of time constants later)?  The values are: ε= 1.4 kV, C = 4.5 µF, R1 = 0.71 M Ω, R2 = R3 = 0.58 M Ω.  Note that 1 M Ω= 106 ohms.  Give your answer in V.

The image shows an electrical circuit diagram. Below is a detailed description of the circuit components and their configuration:

1. **Power Source (ε):** 
   - Represented by a battery symbol on the left side of the diagram with a positive (+) terminal at the top and a negative (-) terminal at the bottom.
   - This provides the electromotive force (EMF) to the circuit.

2. **Resistor (R₁):**
   - Located in series with the power source.
   - Labeled as R₁, this resistor restricts the flow of current in the circuit.

3. **Switch (S):**
   - Positioned after R₁.
   - The switch is shown as an open circuit, indicating that it can interrupt the flow of current.

4. **Parallel Branch:**
   - After the switch, the circuit splits into two parallel branches.

   **First Branch:**
   - Contains a resistor labeled R₂.

   **Second Branch:**
   - Contains a series combination of a resistor (R₃) and a capacitor (C).
   - R₃ is connected in series with the capacitor.
   - The capacitor is labeled as C, representing its ability to store electrical energy.

This configuration is a typical example of a basic electrical circuit used in educational contexts to demonstrate series, parallel, and combined circuit elements. The switch acts as a control to either allow or prevent current from passing into the parallel branches.
