SUMMARY

The discussion centers on calculating the resistance value R0 in a bridge circuit to achieve equality between RAB and R. Participants assert that R0 does not influence the current flow, confirming that RAB will equal R regardless of R0's value. This conclusion highlights the independence of R0 in the circuit's behavior.

In the circuit shown http://www.his.com/~mhtesler/BridgeConfiguration.jpg , what value of R0 will result in RAB being equal to R?

I don't think any current will flow through R0. So it doesn't matter what value it has.
[itex]R_{AB}[/itex] will be R regardless.
 
Very true...
