    We have the Norton pattern in this question but it's better is we transform this into Thévenin, so let's do this: Rth = R1 || R2 Vth = I*Rth

    Let take this parameters as e.g. R1 = 1 ,R2 = 1 So Rth = 1 || 1 = 0.5 Assuming that I=8A, what is the value of the voltage vo (in Volts)? Vth = 8*0.5 = 4, but now if we look at i-v relationship we saw that if the voltage is greatter or equal to 2, the voltage stay at 2 volts. So Answers: 2v Now assuming that I=−3A, what is the value of the voltage vo (in Volts)? Vth = -3*0.5 = -1.5, but now we saw in i-v relationship that it behaves likes a resistor with resistence 1 ohm. Voltage Divider! -1.5*1/(1+0.5) = -1v So Answers: -1v Finally, for the last two parts assume that I=3A What is the value of the voltage vo (in Volts)? Vth = 3*0.5 = 1.5, Voltage divider again! 1.5*1/(1+0.5) = 1v So Answer: 1v What is the value of the voltage v1 (in Volts)? now use Node Method on the original circuit but notice that our nonlinear device Z acts like a resistor(1 ohm) when I = 3v. (v1/R1) - I + v1/(R2+1) = 0 v1 = 2v So Answers: 2v good luck with that!
