### Electrical Circuit: Capacitors and Energy #### Overview: The initial voltages on capacitors C1 and C2 in the circuit have been established by sources not shown. The switch closes at t = 0. #### Circuit Diagram Description: - **Capacitor C1**: - Voltage: 4V - Capacitance: 5µF - **Capacitor C2**: - Voltage: 24V - Capacitance: 20µF - **Resistor**: 250kΩ - **Switch**: Closes at t=0. The circuit configuration: - Capacitor C1 labeled with voltage \(v_1(t)\) - Capacitor C2 labeled with voltage \(v_2(t)\) - Resistor through which the current \(i(t)\) flows. - Voltage across the resistor is \(v(t)\). #### Tasks: a. **Find \(v_1(t)\), \(v_2(t)\), \(v(t)\), and \(i(t)\) for \(t \geq 0\).** b. **Calculate the initial energy stored in capacitors C1 and C2.** c. **Determine how much energy is trapped in the capacitors as \(t \rightarrow \infty\).** d. **Show that the total energy delivered to the 250kΩ resistor equals the difference between the results of part (b) and (c).** This exercise is designed to deepen your understanding of the behavior of capacitors and resistors in a circuit, particularly focusing on voltage changes over time and energy dissipation.
