Introduction to Mesh Current Analysis

In this video, I explain the process of mesh current analysis (aka loop current analysis) for analyzing the voltages and currents in a DC electrical circuit. To understand the process, I work through a simple example.

00:23 - Why mesh current analysis
01:40 - Circuit to analyze
01:59 - Step 1. Identify current loops and assign clockwise current direction
02:31 - Step 2. Label voltage polarities on resistors
03:27 - Step 3. Write Kirchoff's Voltage Law (KVL) equation for each loop
05:34 - Step 4. Collect terms and simplify equations
06:50 - Step 5. solve the system of linear equations for the unknown currents
07:45 - I1 and I2 values
07:50 - Calculate voltages across and current through resistors
09:34 - Confirm calculations
