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 ]
Education tool for post office box exhibited at Tokyo Denki University. The post office box was a Wheatstone bridge–style testing device with pegs and spring arms to close electrical circuits and measure properties of the circuit under test.
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 pedestrian bridge being built over the White River comes with a price tag of $11 million but officials said it is worth the investment to link the Monon and Nickel Plate trails, two of the most ...

However, the method went unrecognised until 1843, when Charles Wheatstone proposed it, in another paper [3] for the Royal Society, for measuring resistance in electrical circuits. Although Wheatstone presented it as Christie's invention, it is his name, rather than Christie's, that is now associated with the device.
