Homework Help: Simple resistor problem

  1. Oct 19, 2012 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations



    3. The attempt at a solution

    What I did was I knew that the their are two resistors in series

    1/req= 1/R + 1/R = 1/2R

    req= 2R

    Where I get confused is how do I include the other resistor since I believe that it is in series?

    The two resistors on the left are in parallel , that is the current splits up through the two branches before going through the last one.

    Wow my addition was off... I figured it out, it is supposed to be 2/R and since like you said it splits up the total resistance would be req=R/2

    R/2 +R = 3R/2
