Question
**Circuit Analysis Overview** Consider \( R = 30 \, \Omega \) for the circuit given below. **Circuit Diagram Description:** 1. **Current Source:** A current source \( 3u(-t) \) A is shown on the left side of the circuit. This indicates a current that is present for \( t < 0 \). 2. **Capacitor:** The current source is connected to a 2.5 μF capacitor. The voltage across this capacitor is labeled as \( v_C \), with the polarities indicated (positive at the top). 3. **2 Ω Resistor:** Following the capacitor, there is a 2 Ω resistor connected in parallel. 4. **Switch:** There is a switch labeled \( t = 0 \), indicating that it changes state at \( t = 0 \). 5. **Inductor:** A 20 mH inductor is connected in parallel to the switch. The current through the inductor is labeled \( i_L \), and the voltage across it is \( v_L \). 6. **Resistor \( R \):** A resistor labeled \( R \) is present, with current \( i_R \) flowing through it. The value of \( R \) is given as 30 Ω. **Task:** Determine \( i_R(0^-) \). (You must provide an answer before moving on to the next part.) The value of \( i_R(0^-) \) is \_\_\_\_\_ A.
