In this video, basic nonlinear circuit element, diode is discussed. The characteristics of Ideal diode, region of operation of diode, resistance levels are discussed. Static resistance and dynamic resistance is treated mathematically. Short circuit test and open circuit test for determining whether diode is in Forward biased or reversed biased region is explained. Four examples were considered to get very clear understanding of determination of region of operation of diode. Equivalent circuits of diodes were discussed which includes ideal diode model, constant voltage drop model, piece wise linear model and small signal model. Problem based on small signal diode is presented in this video.
