1. The problem statement, all variables and given/known data Find the Thorton equivalent of the circuit shown 2. Relevant equations Voc=IscRs Rseries=R1 +R2+..... Rparallel=R1-1+R2-1+.... 3. The attempt at a solution So, I thought I should first solve for the Rsource, by shorting all of the voltage sources: However, I dont think the value I am getting is correct. One value I got is 2111.66 ohms(I combine the 2.2, 2.2, and 5k in series and parallel that with 100k. Then I add the 22k and 22k with the calculated resistance and that is in parallel with the 2.2k)and the other I get is 51663 ohms. (I put the 2.2k from the right with the 2.2k in parallel. Then that combo is in series the other 2.2k and the 5k. That is in parallel with the 100k, and that, finally, is in series with the two 22k) Please, can someone help me?
