a. Calculate the resistance associated with the JFET of Fig. 6.25 for VGS = 0V from ID

Question:

a. Calculate the resistance associated with the JFET of Fig. 6.25 for VGS = 0V from ID = 0 mA to 4 mA.
b. Repeat part (a) for VGS = -0.5 V from ID = 0 to 3 mA.
c. Assigning the label ro to the result of part (a) and rd to that of part (b), use Eq. (6.1) to determine rd and compare to the result of part (b).
