But would it surprise you that you can make an analog device like a slide rule using a Wheatstone bridge — essentially ... divider is one of the easiest circuits in the world to analyze.

half-bridge or full-bridge Wheatstone bridge circuits. Pictured here are tension bars with strain gauges built into them for measuring strain. The one with only one strain gauge is a quarter-bridge.

There are many types of electronic bridges. Examples include a Wheatstone circuit bridge, an H circuit bridge, and a network bridge. Wheatstone circuit bridges are electrical bridge circuits that are ...
