LR Circuit Basics

The video tutorial covers the basics of an LR circuit, including its components: a battery, resistor, inductor, and switch. It explains the initial current in the circuit when the switch is closed and the role of the inductor in opposing changes in current. The concept of steady state current is discussed, where the current reaches its maximum value after a long time. Kirkhoff's loop rule is applied to derive equations for the circuit, and the limits of current and its rate of change are calculated. The tutorial concludes with a summary of the key equations and concepts.
