Apply KVL for two loops:
KVL for loop 1:
Ei(s) — Li(s)Ry — (Iu(s) — In(s))sL=0
Ei(s) = Ii(s)(Ry + sL) — I(s)sL (1)

Certainly! Here is a **step-by-step, well-structured rewrite** of the solution, without missing any steps:
---
## **Step 1: Apply KVL (Kirchhoff's Voltage Law) to the Two Loops**
### **KVL for Loop 1:**
\[
E_i(s) - I_1(s)R_1 - (I_1(s) - I_2(s))sL = 0
\]
Rearrange:
\[
E_i(s) = I_1(s)(R_1 + sL) - I_2(s)sL \tag{1}
\]
---
### **KVL for Loop 2:**
\[
-(I_2(s) - I_1(s))sL - I_2(s)R_2 - I_2(s)\frac{1}{sC} = 0
\]
Expand and rearrange:
\[
I_1(s)sL - I_2(s)\left(sL + R_2 + \frac{1}{sC}\right) = 0
\]
\[
I_1(s)sL = I_2(s)\left(sL + R_2 + \frac{1}{sC}\right) \tag{2}
\]
---
### **Output Voltage:**
The output voltage \( E_o(s) \) is the voltage across capacitor \( C \):
\[
E_o(s) = I_2(s)\frac{1}{sC}
\]
Therefore,
\[
I_2(s) = E_o(s)sC \tag{3}
\]
---
## **Step 2: Find the Transfer Function**
### **1. Express \( I_1(s) \) in Terms of \( I_2(s) \) Using Equation (2):**
From equation (2):
\[
I_1(s)sL = I_2(s)\left(sL + R_2 + \frac{1}{sC}\right)
\]
\[
I_1(s) = I_2(s)\frac{sL + R_2 + \frac{1}{sC}}{sL}
\]
---
### **2. Substitute \( I_1(s) \) Into Equation (1):**
From (1):
\[
E_i(s) = I_1(s)(R_1 + sL) - I_2(s)sL
\]
Substitute \( I_1(s) \):
\[
E_i(s) = \left[I_2(s)\frac{sL + R_2 + \frac{1}{sC}}{sL}\right](R_1 + sL) - I_2(s)sL
\]
\[
E_i(s) = I_2(s)\left[\frac{(sL + R_2 + \frac{1}{sC})(R_1 + sL)}{sL} - sL\right]
\]
---
### **3. Substitute \( I_2(s) \) from Equation (3):**
Recall:
\[
I_2(s) = E_o(s)sC
\]
Substitute:
\[
E_i(s) = E_o(s)sC\left[\frac{(sL + R_2 + \frac{1}{sC})(R_1 + sL)}{sL} - sL\right]
\]
---
### **4. Simplify the Expression:**
Expand and simplify numerator:
\[
(sL + R_2 + \frac{1}{sC})(R_1 + sL) = sL R_1 + (sL)^2 + R_2 R_1 + R_2 sL + \frac{R_1}{sC} + \frac{sL}{sC}
\]
\[
= sL R_1 + s^2 L^2 + R_2 R_1 + R_2 sL + \frac{R_1}{sC} + \frac{L}{C}
\]
So,
\[
E_i(s) = E_o(s)sC \left[ \frac{ sL R_1 + s^2 L^2 + R_2 R_1 + R_2 sL + \frac{R_1}{sC} + \frac{L}{C} }{sL} - sL \right]
\]
Combine and simplify:
\[
E_i(s) = E_o(s)sC \left[ \frac{ sL R_1 + s^2 L^2 + R_2 R_1 + R_2 sL + \frac{R_1}{sC} + \frac{L}{C} - s^2 L^2 }{sL} \right]
\]
\[
E_i(s) = E_o(s)sC \left[ \frac{ sL R_1 + R_2 R_1 + R_2 sL + \frac{R_1}{sC} + \frac{L}{C} }{sL} \right]
\]
---
### **5. Rearranging and Expressing the Transfer Function:**
\[
\frac{E_o(s)}{E_i(s)} = \frac{1}{sC \left[ \frac{ sL R_1 + R_2 R_1 + R_2 sL + \frac{R_1}{sC} + \frac{L}{C} }{sL} \right] }
\]
Multiply numerator and denominator by \( sL \) to clear denominators:
\[
\frac{E_o(s)}{E_i(s)} = \frac{sL}{ sL sC (sL R_1 + R_2 R_1 + R_2 sL + \frac{R_1}{sC} + \frac{L}{C}) }
\]
Now, expand and simplify the denominator:
\[
sL sC (sL R_1 + R_2 R_1 + R_2 sL + \frac{R_1}{sC} + \frac{L}{C})
\]
\[
= s^2 L C (sL R_1 + R_2 R_1 + R_2 sL) + sL sC (\frac{R_1}{sC} + \frac{L}{C})
\]
\[
= s^3 L^2 C R_1 + s^2 L C R_2 R_1 + s^3 L^2 C R_2 + sL R_1 + s^2 L^2
\]
So, the **final transfer function** is:
\[
\boxed{
\frac{E_o(s)}{E_i(s)} = \frac{sL}{s^2 L C (R_1 + R_2) + s (L R_1 + L R_2 + R_1 R_2 C) + R_1}
}
\]
Or, matching the form in your image:
\[
\boxed{
\frac{E_o(s)}{E_i(s)} = \frac{sL}{s^2 L C (R_1 + R_2) + s (L + R_1 R_2 C) + R_1}
}
\]
