Time Constant - LR Circuit

The video tutorial covers the concept of time constants in LR circuits. It begins with a recap of previous lessons on deriving equations for current and its rate of change. The instructor explains the significance of the time constant, which is the time it takes for a 63.2% change in the variable. The video also includes a graphical interpretation of how current and its rate of change behave over time in an LR circuit. The tutorial concludes with a detailed discussion on the time constant's role in these graphs, emphasizing its importance in understanding circuit behavior.
