1. The problem statement, all variables and given/known data Here's the problem: Find the equivalent conductance Geq and then the equivalent resistance Req "seen" by the current source Is in the circuit in terms of the literals R1, R2, and gm. Figure: 2. Relevant equations Ohm's Law: V = IR KVL: V1 + V2 + ... Vn = 0 for closed loops KCL: I1 + I2 + ... In = 0 going in an out of a node Voltage Division: V1 = Vsource * (R1/(R1+R2)) 3. The attempt at a solution I wasn't really sure how to go about this one. I know that Req = Vs/Is, so I set about trying to find a way to get that in terms of the given values, but to no avail- I don't know whether to treat this as a series circuit or parallel based on the independent source (since if it's parallel one of the paths is just the dependent current source with no resistors). I tried using voltage division to solve for Vx, but I don't really know what good that will do me, or if I even can do that in this situation. I'd really appreciate some direction here. Thanks.
