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.
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. :/
