Answers:
R₁ = 3.86 k-ohm
R_D = 1.2 k-ohm

Answers:
I_D = 2.62 mA
V_GS = 2.14 V
V_DS = 5.85 V

Answers:
I_D = 0.78 mA
V_GS = 1.04 V
V_DS = 3.05 V

Answers:
R_S = 3.25 k-ohm
R_D = 5 k-ohm

Answer:
R_D = 4.88 k-ohm

Answers:
I_D = -[V_DS / 1.5 ] + 2
y-intercept = 2 mA, x-intercept = 3 V
Q-point = ( 2.52 V, 0.3168 mA)

Answers:
R_D = 1 k-ohm
I_D = 11 mA
