## Homework Statement

Assuming R = R' = 1.97 Ω in the network shown above, determine the net resistance

a) between the points a and c

b) between points a and b.

HELP: Use symmetry.

HELP: Imagine applying a voltage between a and c and think about what current will flow in each resistor.

## Homework Equations

Series: R

_{total}=R

_{1}+R

_{2}

Parallel: R

_{total}=(R

_{1}

^{-1}+R

_{2}

^{-1})

^{-1}

## The Attempt at a Solution

Well, I redrew the series in my notebook as parallel and series, but in both attempts at a re-draw, I ended up with a weird branch that wasn't really either series or parallel, because of how it connected. I tried solving it anyway (and have come up with 1.313 for the resistance between a and c) but nothing's been right. I'm just not sure what to do with the weird branch. :/
