### Problem 5: Transient and Steady-State Response in RC Circuit #### Problem Statement: Consider the circuit diagram below. Find \(I_x(t)\) for \(t < 0\) and \(t \ge 0\). #### Given Circuit Description: - A DC voltage source of 36 V is connected in series with a 2 kΩ resistor. - This series combination is connected in parallel with a 100 μF capacitor. - The capacitor is connected in series with a 6 kΩ resistor. - At the junction between the 6 kΩ resistor and the capacitor, there is a branch containing a switch and a 3 kΩ resistor. The switch is initially open. - The switch closes at \(t = 0\), connecting the 3 kΩ resistor into the circuit. - This branch is connected in parallel to a 4 kΩ resistor and a 12 V DC voltage source. - The current \(I_x\) flows through the 6 kΩ resistor. #### Diagram Explanation: 1. **36V Voltage Source**: - Shown on the left side supplying 36 V. 2. **2 kΩ Resistor**: - Connected immediately in series with the 36V source. 3. **100 μF Capacitor**: - Connected in parallel to the 2 kΩ resistor and the parallel branch contains the capacitor and the 6 kΩ resistor. 4. **6 kΩ Resistor**: - Series connection with the mentioned capacitor. - Current \(I_x\) flows through this resistor. 5. **Switch and 3 kΩ Resistor**: - This branch becomes active when the switch closes at \(t = 0\). - Initially open, thus not affecting the circuit for \(t < 0\). 6. **4 kΩ Resistor and 12V Voltage Source**: - Another parallel branch with respect to the 6 kΩ resistor and the switch, connected in parallel with a 4 kΩ resistor and 12V voltage source. #### Required Analysis: - **For \(t < 0\)**: - Determine the steady-state current \(I_x\) through the 6 kΩ resistor before the switch closes. - **For \(t \ge 0\)**: - Determine the transient and steady-state current \(I_x(t)\) after the switch has closed. ### General Approach
