## Homework Statement

Find the equivalent resistance between A and B. All resistances shown are in ohm.

## Homework Equations

The formulas for parallel and series connections.

## The Attempt at a Solution

I have attempted to redraw the circuit and my redrawn diagram looks like this.

I don't think it's correct,because I'm not getting the correct answer from this circuit diagram.

The only troublesome part is the 5 ohm resistor. My idea is that no current passes through it. If I make that assumption,then the answer comes out beautifully. Do I sniff a Wheatstone bridge (and zero potential difference) somewhere?
