I came across a problem while searching for extra problems on the internet for practice.and came across one im having trouble with. I know to figure out a equivalent circuit, we need to find Voc(open circuit across load) and Isc(short circuit across load) to then figure out rL =(Voc/Isc).
Problem 1)
using nodal analysis,and current leaving is positive as my convention.
I decided to source transform the 4A independent source with the 4ohm resistor in parallel to a 16V source with a 4 ohm resistor in series.To try and reduce the nodes for nodal analysis.
But I kinda get stuck with the 2V source,I know itd be difficult to figure out a KCL since the 2V source doesn't have a resistance to divide by. I would like to apply nodal analysis at A and B's nodes. I just having trouble simplifying the circuit.Any help would be appreciated.
I have another problem after this,but ill post once I figure this puppy out
