By watching this video, you will learn the following topics: 1:01 Construction of n-channel JFET 2:25 Working of n-channel JFET 6:01 Output characteristics (Drain curves) of n-channel JFET 11:07 Different regions of operation of JFET 13:07 p-channel JFET 14:44 Symbols of n-channel and p-channel JFET JFET (Junction Field Effect Transistor) : The junction field Effect Transistor (JFET) is used in a wide range of applications. It is a three terminal device. (The 3 terminals are Gate, Drain, and Source) JFET can be classified as either n-channel JFET or p-channel JFET. n-channel JFET: In the n-channel JFET, the channel is made up of n-type semiconductor material and two small p-type regions are formed near the channel. p-channel JFET: In the p-channel JFET, the channel is made up of p-type semiconductor material and two small
