Hey guys, we are currently doing FETS again in class and there is something i dont understand. IN the schematic i have attached, the question asks to design this circuit for Id to be 1mA. I dont understand how this is possible as the internal resistance of the FET is 100kOhm. for 1mA to flow through the FET, the way i see it (which is completely wrong) is that the voltage across it will be (1mA * 100000) which is ridiculous and not the 10 volt my lecturer got.
My lecturer kep saying something about the resistances being in parallel and i completely understand this from the output impedance point of view (looking in from the vout) but without this circuit connected to anything, how does this work?
Help , i am lost!
