A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component. The primary benefit of the circuit is its ability to provide extremely accurate measurements (in contrast with something like a simple voltage divider ). [ 1 ]

A Wheatstone bridge is a configuration of four balanced resistors with a known excitation voltage applied as shown below: Excitation voltage V EX {\displaystyle V_{\text{EX}}} is a known constant and output voltage V o {\textstyle V_{o}} is variable depending on the shape of the strain gauges.
Joseph Albert Britton (1839–1929), [1] most commonly known as J.A. Britton, was a builder of bridges in Indiana. He created many works that survive and are listed on the U.S. National Register of Historic Places .

A standard Wheatstone bridge for comparison. Points A, B, C and D in both circuit diagrams correspond. X and Y correspond to R 1 and R 2, P and Q correspond to R 3 and R X. Note that with the Carey Foster bridge, we are measuring R 1 rather than R X. Let ℓ 1 be the null point D on the bridge wire EF in percent.
A man live-streamed a police chase and standoff on a bridge at I-35W and Loop 820 in Fort Worth on Thursday, Aug. 8, 2024. The major interchange was shut down for several hours.
