Rearranging, we get Rx = (R2*R3)/R1, and solving, we get (8*6)/4=12 ohms ... the more common diamond shape for a Wheatstone bridge. When we turn on the circuit, the galvanometer would likely ...

The National Transportation Safety Board has identified six Ohio bridges that could be at risk of collapse if they sustained a boat collision similar to one in Maryland last year. The NTSB report ...

A Wheatstone bridge is one of those handy circuits that has plenty of uses in both AC and DC measurements. We probably see them most often in a strain gauge.
