Kirchhoff's Laws and Circuit Analysis

The video tutorial explains how to find the current in a 6 Ohm resistor using M analysis. It begins by introducing the circuit and defining the currents I1 and I2. The Kirchhoff's Voltage Law (KVL) is applied to set up two equations. These equations are then solved to find the values of I1 and I2. Finally, the current through the 6 Ohm resistor is calculated by subtracting I2 from I1, resulting in a current of 2.8 amperes.
