  1. In following figure find VDSQ by assuming gate current is negligible for the p-channel JFET. (if IDQ = - 6 mA, RS = 0, VDD = -18 V, RD = 2 kΩ, IDSS = - 10 mA, IPO = - 3 V)

  2. A.
    4 V
    B.
    - 6 V
    C.
    - 10 V
    D.
    6 V

    Answer : Option B

    Explanation :

    By Appling KVL around drain source loop.

    VDSQ = -18 - (-6). 2 x 103 = - 18 + 12 k x 10-3 -6 V.
