1. The problem statement, all variables and given/known data Find Rth, at the terminals shown on the diagram 2. Relevant equations Series resistance = R1 + R2 + R3 +.... Parallel Resistance = 1/((1/R1)+(1/R2)...)) 3. The attempt at a solution When attempting problems like this, I was told by teachers and the text book to start at the opposite end of the terminals(where the Rth and arrow is). So in that case I combine the two 6 kohms resistors together (in series), and then combine that with the 3 ohms resistor (in parallel), getting an answer of 2.4 kohms, different to the answer provided.. In the answer provided, they don't start at the opposite end of the terminals, instead they start near the terminals. Is there something I'm not understanding right? or is the answer wrong?
