Question
The circuit diagram provided consists of the following components:

- **Resistors:** 
  - R1 with a resistance of 2.2 kΩ
  - R2 with a resistance of 250 Ω

- **Capacitors:**
  - C1 with a capacitance of 200 nF
  - C2 with a capacitance of 800 nF

- **Voltage Sources:**
  - A 40 V source on the left
  - An 80 V source on the right

- **Switch:**
  - The switch in the circuit has been in the left position for a long time before moving to the right at time \( t = 0 \) and remains there.

**Variables of Interest:**

- \( v_0(t) \): Voltage across the capacitor C1
- \( i_0(t) \): Current through resistor R2
- \( v_1(t) \): Voltage across resistor R1
- \( v_2(t) \): Voltage across capacitor C2

**Objective:**

Find the following quantities:

(a) \( v_0(t) \)

(b) \( i_0(t) \)

(c) \( v_1(t) \)

(d) \( v_2(t) \)

(e) The energy trapped in the capacitors as \( t \to \infty \). 

The importance of analyzing such a circuit lies in understanding the transient and steady-state behavior of electrical circuits with switched capacitors. This analysis is critical in various applications like filter design, analog circuits, and signal processing.
