Nonlinear Circuits: Diodes

This lecture introduces the concept of nonlinear circuits, focusing on diodes as an example. The instructor explains how the relationship between voltage and current in these circuits is not linear, contrasting it with linear circuits. By analyzing the graphical representation of a circuit with a diode, the lecture demonstrates how to determine the operating point and current flow. Through a step-by-step approach, the instructor shows how to use graphical methods to solve for current values in circuits containing diodes, providing practical examples and exercises for further understanding.
