1. The problem statement, all variables and given/known data Find the Thévenin equivalent of the circuit shown in FIGURE 1. 2. Relevant equations Any two-terminal network can be replaced by an equivalent circuit consisting of a voltage source and a series resistance equal to the internal resistance seen looking into the two terminals. 3. The attempt at a solution Figures 2 & 3 I'm unable to figure out how to proceed from here or if what i've done so far is correct. Can't seem to find any examples anywhere of anything similar . Any help or useful sites would be much appreciated.
