1. The problem statement, all variables and given/known data For the linear circuit shown, given that the current I in the 0.9 K[tex]\Omega[/tex] is 10mA when Vs = 100V: (a) Predict I using the proportionality property for: Vs = 25V, -12V, and 145 V respectively. (b) Use Thevenin’s theorem across terminals a and b. Find I in terms of Vs and hence calculate I for the various values of Vs in (a). 2. Relevant equations V = IR Thevenin's Theorem 3. The attempt at a solution I really don't know where to begin with this one. I'm lost for part (a), and for part (b), while I understand Thevenin's theorem, I'm just not seeing how to apply it to branch a-b. If anyone can help me get going with this question, I would be very grateful. Thanks.
