You said R_DS does not depend on top resistor, but to calculate it, we needed the current, which we used the top resistor to calculate. So wouldnt the R_DS be implicitly set by the resistor if we need to calculate current?
@@MasterDomai coming from the future, if you plan to get the FE exam done you will need to know Rth, since some questions will make you take a Nodal view from the ground and Rth comes into play during that. Some Nasty stuff
I love your slightly sadistic tone it makes the video so much fun to watch!
Your explanation left more questions than answers

thank you for the video, actually it was a quick and nice recap of JFET for me
A diode is in series with 220V. If the voltage across the resistors is 6V. Find the current through the diode?.
thank you so much
Makes this seem so easy lol
a goodwork
Why subtract 0 to 8.3? Thank you
Current is from high to low
nice video , too bad about the distortion on the microphone
Vd is zero according to the first calculation?
I believe your right. The first formula should subtract the voltage deopped over the jfet. I'm beginning to question whats accurate in this video.
Its true if Id (current in drain) is on saturation, Vd is always equal to 0..
Something does not add up here.
why dou you calculate Rth? we know that gate current is equal to zero... if gate current is zero
May be it will help us to know the input impedance of the whole cascade lately - the Rth II Zin ~ Rth

I had thought Vth is always connected to a series Rth. But for Nodal it's I(nodal) in parallel with Rth=R(nodal)
Its mega ohm or micro ohm
mega
Why do you keep asking, "Is it fun?", meanwhile making it more complicated for beginners lol.
