Transcribed Image Text:**Title: Analysis of Circuit Response After Switching Operation**
**Objective:**
To determine the type of response displayed by the circuit shown in Figure 9 after the switching operation occurs at \( t = 0 \).
**Problem Statement:**
At \( t = 0 \), a switching operation occurs which produces the circuit shown in Figure 9. We are given the initial conditions where \( i_{L1}(0) = 1 \text{A} \) and \( v_C(0) = 50 \text{V} \). What type of response is displayed after the switching operation?
**Circuit Description (Figure 9):**
* **Components:**
* Two inductors, each with an inductance of 100 mH.
* One capacitor with a capacitance of 55 µF.
* Two resistors with resistances of 50 Ω and 75 Ω, respectively.
* **Circuit Layout:**
* The two inductors (100 mH each) are connected in series.
* The series combination of the inductors is then connected in parallel with the capacitor (55 µF).
* The resistor with 50 Ω resistance is connected in series with the parallel combination of inductors and capacitor.
* The resistor with 75 Ω resistance is connected in series at the bottom part of the circuit layout.
**Variables:**
* \( i_{L1} \) - Current through the first inductor.
* \( v_C \) - Voltage across the capacitor.
**Initial Conditions:**
* \( i_{L1}(0) = 1 \text{A} \)
* \( v_C(0) = 50 \text{V} \)
**Objective:**
To analyze and determine the type of response (type of damping) that the circuit will display after the switching operation.
---
**Explanation:**
The given circuit is an RLC (Resistor-Inductor-Capacitor) circuit. When the switch operates at \( t = 0 \), the circuit will exhibit a response based on the interaction between resistances, inductances, and capacitance.
1. **Determine the Equivalent Inductance (\( L_{eq} \)):**
Since the two inductors are in series, the total inductance is the sum of the individual inductances:
\[
L_{eq} = L1 + L2 = 100 \text{mH} +
