Homework Help: What is the equivalent resistance from A to B?

  1. Dec 13, 2015 #1
    1. The problem statement, all variables and given/known data
    R = 10 Ohms
    2. Relevant equations
    Req = (1/R1 + 1/R2 + ... )(-1)

    Req = R1 + R2 + ...
    3. The attempt at a solution
    I honestly don't even know where to start...

    The obvious thing to do is

    4R + 2R = 6R

    That's pretty much all I can come up with that makes sense... Any help?

    Perhaps it would help to start reducing obvious series and/or parallel resistor sets.
