    In the op amp circuit it asks for VL I use the V Ref from the zener am I missing something else to solve for VL?

    I'll try and redo the schenatics tomorrow,

    I copied off blackboard and one was attached to an e-mail.

    I was trying to determine to solve for V L when the zener was referencing 24V if there was a formula to solve for VL

    Yes but the VGG polarity is backwards and the VDD = 20v

    R2 = 7k
    What I'm looking for is if I'm given the drain current there are a lot of practice exercies where they give me the Q drain current and to find theQ drain voltage
    in this example they give me 1mA drain current.

    I have been using VD = VDD -IDDS RD

    20V-(1mA)(7k) = 13

    No I'm getting these problems from Army radar repair tech's. I'm trying to prepare myself for a future training course I may have to take.

    I'm in the process of trying to learn the basic of electronics, for the course they use the Navy books as a reference.

    So they keep changing things in the circuits so I can practice the basics.
    thanks joe
