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 Another Mesh Current Example:    • Mesh Current Analysis Example
