Homework Help: Question on Thevenin Circuit

  1. Jan 31, 2014 #1

    Can someone explain (in terms of the voltage and current if possible), why R3 and R2 are in parallel and why R1 and R3 are in series?

    Hi influx. It is not really correct to state any one of these resistors to be in series with another one here.

    It often is clearer if you think in terms of parallel and series paths. If you can find a route that allows current to flow from one end of a resistor to the [node at the] other end of that resistor, and without passing through that resistor, you have found a parallel path.

    If all current that passes through a particular resistor must also pass through another resistor (and vice-versa) then those two resistors are in series.
