**1. The problem statement, all variables and given/known data**

See this image: http://ift.tt/1dcVSEo

I need to find the equivalent resistance of this circuit, I can find the amps/voltage drop myself but I don”t understand how to distinguish between parallel and series in this kind of circuit.

**2. Relevant equations**

Ohm’s Law: I (amps) * R (resistance) = V (voltage)

Volt = E/Q (energy / charge)

Resistance = (p (roe/resistivity) * length)/ area

R^-1 = r1^-1 + r2^-1

**3. The attempt at a solution**

I don’t have a good attempt to show, but It must have something to do with eliminating the inside triangle to make it a series.

Here’s my idea :http://ift.tt/1eRWs6Y
