a. Calculate the resistance associated with the JFET of Fig. 6.22 for V_GS = 0 V from I_D = 0 mA to 4 mA.

b. Repeat part (a) for V_GS = −0.5 V from I_D = 0 to 3 mA.

c. Assigning the label r_o to the result of part (a) and r_d to that of part (b), use Eq. (6.1), to determine r_d and compare to the result of part (b).
