Nodal Analysis

In the analysis of any electric circuit, nodal analysis is the method of determining the potential difference or voltage between different nodes in an electric circuit. A node is a point where two or more branches connect each other. In the nodal analysis, the voltages are determined in the terms of branch currents. The nodal analysis is also known as the node voltage method or branch current method. The nodal analysis method is one of the several applications of Kirchhoff's Current Law (KCL).

Question

## Exercise: Circuit Analysis Using Loop Analysis

**Objective:** For the circuit below, use loop analysis to find the voltages \( V_A, V_B, \) and \( V_C \). (Provide your calculations and reasoning for your answer.)

**Instructions:** Use matrix form to solve the equations.

### Circuit Diagram Description

- **Voltage Sources:**
- \( V2 = 25 \text{Vdc} \)
- \( V3 = 15 \text{Vdc} \)

- **Resistors:**
- \( R8 = 1k \Omega \)
- \( R9 = 220 \Omega \)
- \( R10 = 330 \Omega \)
- \( R11 = 4k \Omega \)
- \( R12 = 700 \Omega \)
- \( R13 = 470 \Omega \)
- \( R14 = 550 \Omega \)
- \( R15 = 2k \Omega \)

- The diagram is a complex loop circuit where the voltages \( V_A, V_B, \) and \( V_C \) need to be determined.

### Diagram Explanation

The diagram illustrates three loops with nodes labeled \( V_A, V_B, \) and \( V_C \). The circuit comprises multiple resistors and two voltage sources positioned as follows:

1. 25V source (\( V2 \)) is located at the bottom left.
2. 15V source (\( V3 \)) is located at the bottom right.
3. Resistors connect the various nodes, creating paths for current to flow, and loops for analysis.

### Solution

1. **Formulate the Loop Equations:**
- Apply Kirchhoff’s Voltage Law (KVL) to each loop.
- Create equations based on the sum of voltage drops across each component equaling the sum of voltages supplied.

2. **Use Matrix Form:**
- Express the loop equations in matrix form.
- Solve for the unknown voltages \( V_A, V_B, \) and \( V_C \).

3. **Perform Calculations:**
- Utilize mathematical software or manual calculation methods to find voltages.

By understanding how to set up and solve these loop equations, you can analyze complex circuits efficiently. The matrix method allows for systematic calculation, aiding in both manual problem-solving and computational approaches.
