Norton Theorem
In the current circuit law, the Norton theorem (also known as the Mayer-Norton theorem) is a simplification that can be applied to networks generated by a constant line of opposition, power sources, and current assets. In two network terminals, it can be…
Question
**Circuit Analysis Problem** 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. **Circuit Description:** The circuit consists of three voltage sources and several resistors. Here is a breakdown of the components and their connections in the circuit: 1. **Voltage Sources:** - \( V2 = 25 \text{Vdc} \) located on the left side of the circuit. - \( V3 = 15 \text{Vdc} \) located on the right side of the circuit. 2. **Resistors and Their Values:** - \( R8 = 1k \Omega \) connected to \( V2 \). - \( R9 = 220 \Omega \) connected between \( V_B \) and \( V_C \). - \( R10 = 330 \Omega \) located at the top path connecting to \( V_A \). - \( R11 = 4k \Omega \) located at the top right path. - \( R12 = 700 \Omega \) connected between \( V_C \) and \( V3 \). - \( R13 = 470 \Omega \) connected between \( V_A \) and \( V_C \). - \( R14 = 550 \Omega \) located below \( V_C \). - \( R15 = 2k \Omega \) connecting \( V_B \) downward. 3. **Node Voltages:** - \( V_A \): Voltage at the top right node. - \( V_B \): Voltage at the middle left node. - \( V_C \): Voltage at the bottom middle node. 4. **Ground Connection:** - There is a ground symbol below the circuit, indicating the reference point for voltage. **Instruction:** - Use loop analysis (also known as mesh analysis) to find \( V_A \), \( V_B \), and \( V_C \). - Apply Kirchhoff’s Voltage Law (KVL) to write equations for each loop. - Solve the system of equations to find the unknown voltages. **Note:** Through loop analysis, pay attention to the direction of current flow and the polarities of the voltages for each component in the loops defined.
