Piecewise Linear Diode Models

The video tutorial explains the piecewise linear model, also known as the Battery Plus resistance model, which is a more accurate representation of a diode compared to the ideal diode assumption. The model approximates the diode's exponential characteristic curve with linear segments. It consists of an ideal diode, a voltage source, and a resistor in series. The tutorial derives the diode current equation using Kirchhoff's Voltage Law (KVL) and explains how to plot the current-voltage characteristic curve, comparing the exponential and linear approximations.
