Answer: v₂ = (3/2) v₁

Answers:
v_a = -3.6 V
v_b = – 6 V
v_c = -5.45 V
v_o = -23.95 V

Answers:
R₂ = 20 k-ohm
Power dissipated = 50 mW
Gain = -10

Answers:
R₁ = 50 k-ohm
R₂ = 500 k-ohm

Answers:
Gain = -2
v_o = -3 V

Answers:
i) vo = -10V, i₁ = 1 mA, i₂ = 1 mA
i_L = -10mA and i_o = -11 mA
ii) voltage gain = -10

Answers:
i) vo = 6 V, i_O = 1.9 mA
ii) R₁=112.5 k-ohm and R₂ = 1.5 k-ohm

Answers: v_o = -11.52 V
