How do you find the current in a circuit using mesh analysis?
Summary
- Identify the meshes.
- Assign a current variable to each mesh, using a consistent direction (clockwise or counterclockwise).
- Write Kirchhoff’s Voltage Law around each mesh.
- Solve the resulting system of equations for all loop currents.
- Solve for any element currents and voltages you want using Ohm’s Law.
What is the relationship between mesh current and branch current?
It is an actual current flow through the branch. A mesh current is an assumed current to flow around a mesh without branching. The mesh current won’t divide at the branch point.
How many current mesh currents are in the circuit?
The three currents are all drawn in the same direction, clockwise. One KVL equation is written for each of the three loops. Note that there is no polarity drawn on the resistors.
How do you solve mesh analysis problems?
In the first phase, find out the meshes and mark out the mesh currents either in the anti-clockwise or clockwise directions. Look into the amount of current flow that flows through each element corresponding to mesh currents. To find out the mesh currents, solve the observed mesh equations as per step 3.
Is KVL and mesh analysis same?
Mesh analysis employs KVL (Equation 10.1) to generate the equations that lead to the circuit currents and voltages. In mesh analysis you write equations based on voltages in the loop but solve for loop currents.

Steps to solve mesh analysis method
- Make sure that the circuit considered for analysis has only voltage sources.
- Label the nodes with either numbers or alphabets.
- Assign the mesh currents in each loop, such that all the current directions are in a clockwise direction.
