How to solve mesh analysis using the calculator
292KHello everyone! Today, I’m excited to teach you how to solve mesh analysis using a calculator. Mesh analysis is a powerful circuit analysis technique that allows us to analyze complex electrical circuits with multiple loops. By applying Kirchhoff’s voltage law to each mesh in the circuit, we can find the current flowing through each branch and the voltage across each component. This method is particularly useful when dealing with circuits that have numerous components and sources.
To demonstrate how to solve mesh analysis using a calculator, I will walk you through a step-by-step example. Let’s consider the following circuit:

Before we begin, it’s important to understand the basics of mesh analysis. A mesh is a closed loop in the circuit that does not contain any other loops. The number of meshes in a circuit is equal to the number of essential nodes minus one. In our example circuit, there are two meshes because there are three essential nodes (A, B, and C).
To solve mesh analysis using a calculator, follow these steps:
Step 1: Label the meshes in the circuit. In our example, we will label the two meshes as mesh 1 and mesh 2.
Step 2: Assign currents to each mesh. Choose a direction for the current in each mesh. For mesh 1, let’s assign the current as I1 flowing clockwise. For mesh 2, let’s assign the current as I2 flowing counterclockwise.
Step 3: Write Kirchhoff’s voltage law equation for each mesh. Kirchhoff’s voltage law states that the algebraic sum of the voltages around any closed loop in a circuit is equal to zero. Write the equation for each mesh by summing the voltage drops and sources in that loop.
For mesh 1:
V1 = R1*I1 + R2*(I1-I2) + V1
For mesh 2:
V2 = R3*I2 + R2*(I2-I1) + V2
Step 4: Simplify the equations. Combine like terms and solve for the unknown currents. In our example, we have two equations with two unknowns (I1 and I2). Use a calculator to solve the equations simultaneously.
Step 5: Calculate the voltage across each component. Once you have found the currents in each mesh, you can calculate the voltage drop across each component using Ohm’s law (V = I*R).
By following these steps, you can easily solve mesh analysis problems using a calculator. This method is efficient and accurate, especially for larger circuits with multiple loops. Practice and familiarity with circuit analysis techniques will help you become proficient in solving complex electrical circuits.
I hope this tutorial has been helpful in demonstrating how to solve mesh analysis using a calculator. Remember to practice and apply these techniques in your circuit analysis projects for success. Thank you for watching!
