FIND THE CURRENT ON RESISTOR R2 (NEED NEAT HANDWRITTEN SOLUTION ONLY OTHERWISE DOWNVOTE).

**Problem Statement:**

The capacitor in the circuit is initially uncharged, and the switch \( S \) is suddenly closed at \( t = 0 \). Find the current through resistor \( R_2 \) at \( t = \infty \). Given \( R_1 = 4R \) and \( R_2 = 3R \).

**Answer Choices:**
A) \(\frac{\mathcal{E}}{R}\)
B) \(\frac{\mathcal{E}}{2R}\)
C) \(\frac{2\mathcal{E}}{3R}\)
D) \(\frac{\mathcal{E}}{4R}\)
E) \(\frac{4\mathcal{E}}{3R}\)

**Circuit Diagram Description:**

The circuit schematic provided includes the following components:
- A switch \( S \) that controls the circuit.
- A resistor \( R_1 \) in series with the switch \( S \).
- A power source with voltage \( \mathcal{E} \).
- A parallel combination of a resistor \( R_2 \) and a capacitor \( C \).

The voltage source \( \mathcal{E} \) is connected to the parallel combination of \( R_2 \) and \( C \) through the series resistor \( R_1 \).

**Explanation:**

1. **Initial Condition at \( t = 0 \):**
    - The capacitor \( C \) is initially uncharged, so it behaves like a short circuit (wire) at the moment the switch is closed.

2. **As \( t \to \infty \):**
    - The capacitor \( C \) will be fully charged and will behave like an open circuit.
    - Current will only flow through resistors \( R_1 \) and \( R_2 \) in series.

3. **Resistor Values:**
    - \( R_1 = 4R \)
    - \( R_2 = 3R \)

4. **Simplifying the Circuit for \( t = \infty \):**
    - The total resistance in the circuit, which is the sum of \( R_1 \) and \( R_2 \), will be:
      \[
      R_{\text{total}} = R_1 + R_2 = 4R + 3R = 7R
