Hello uart! Thank you very much for your reply! That is very inspirational and reassuring! Thank you for quoting some real-world examples which would produce negative Thevenin resistances! gta100

Hello rude man! Thank you for your reply. I have determined i(R) for sure. It is Vth/(R + Rth), right? I actually included it in the formula for the power transferred to the load resistor, namely, P = R*(Vth/(R + Rth))^2. I even plotted the equation in MATLAB, and it turned out that P will...

Hi Berkeman! Sure! Let me go ahead and post a sample circuit for you (Please see attachment). So in this circuit, I find Rth = -15000/11 ohms = - 1363.636364 ohms , and Vth = - 2680/11 V (Also negative). I need to find the maximum power transfer to the rheostat R as indicated. Thank you...

Hello berkeman! Thank you very much for your reply! By negative Thevenin resistance, I mean Rth < 0 in the Thevenin equivalent circuit. According to my textbook, negative Rth may appear when there are ONLY DEPENDENT sources inside "the circuit". By "the circuit", I mean the circuitry with...

Hello everyone! I have a general question about how to find out the maximum power transfer to a load resistor with a negative Thevenin Resistance (Rth < 0). I know for positive cases, P = R*(Vth/(R + Rth))^2, in which R is the load resistor connected to the Thevenin equivalence circuit, and Pmax...
