    in terms of an practical exercise it is required to do a electric
    circuitry consisting of an parallel-circuitry between one J-FET and one
    non voltage dependent resistor. The first component (J-FET) ist
    operatet (biassed) up to maximum pinch-off current (current drain = 0).
    The resulting point of this pinch-off-state should be wired as the
    drain-connection. This is not an big task, so your help would be very
    appreciated as far as circuitry-design is concerned. An solution with
    simulation software such as PSpice would be good for me as well.

    Please give me a hint.

  2. If the FET is off and the resistor is in parallel, then just model the
    combination as the resistor alone. Sounds like a homework problem.

    Yes, but I need some parameters of the complete construction. So I have
    to use J-FET and resistor.

    If your teacher is not able to explain the assignment well enough for you
    to complete it, then you need a new teacher.

    Good Luck!
