JFET: Construction and Working Explained 

In this video, the construction and working of n-channel JFET and p-channel JFET are explained.
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 n-type regions are formed near the channel.
In this video, the construction and working of JFET are explained by taking the example of n-channel JFET. And at the latter part of the video, the output characteristics (Drain curves) and the different region of operation of JFET is also discussed.
Different regions of operation of JFET:
1) Ohmic region
2) Saturation Region
3) Cut-off Region
4) Breakdown Region
This video will be helpful to all students of science and engineering in understanding the construction and working of JFET.
