i never did the topic before..it's something newAll of the values are static and easily determined in the absence of any AC inputs.
i'm cofusing this with the jfetThat gives us nothing to go on. We will not do your homework for you. You need to show YOUR best attempt to solve the problem. We can then look it over and point out where you are making a mistake or give a hint on what you might need to consider. But YOU need to do the work.
you mean the one on my question is not an N depletionThe transistor in Post #4 looks like a typical enhance type MOSFET to me.
Below is a similar circuit with a JFET.

You should probably become familiar with the the main differences between the two types of FET mentioned.
Start with the governing equations. For a depletion mode NFET, what is the relationship between the various voltages and currents?i'm cofusing this with the jfet
i failing to do it.....i've just changed the programme...so it's something newStart with the governing equations. For a depletion mode NFET, what is the relationship between the various voltages and currents?
thanks ...do you have mosfets noteshi mara,
I found a couple of my old PDF's ref JFets' , it may help.

If you know that the current into and out of the gate is zero, or so close to zero as to not be worth worrying about, then all of the DC currents in the gate circuit must flow through the resistors, does that help? It should because Ohm's law will tell you the current through the resistors, whose values are known, if you know the voltage across them.i never did the topic before..it's something new
A depletion mode MOSFET is similar to a JFET except that positive Vgs will increase drain current.i'm cofusing this with the jfet
So look in your textbook, or wherever, for the equations that govern the behavior (the voltage/current relationship) for a depletion mode MOSFET. Stop just expecting others to spoon feed you the basic information you are supposed to be learning.i failing to do it.....i've just changed the programme...so it's something new
So you are saying that the answer is exactly the same whether the FET is enhancement mode or depletion mode, or whether the device is N-channel or P-channel? Or if the device is a VCCS or a VCVS?Actually, there is enough info given to calculate the answers for any black box if you assume the gate is insulated from the drain. You do not need to know anything about the device.
