Divide and Multiply with a Wheatstone Bridge
A two-page article from Radio-Electronics (June 1960) by Forrest H. Frantz Sr. describing how a properly configured Wheatstone bridge circuit can function as a simple analog calculator for multiplication and division. The article presents the bridge resistance relationship (A/B = C/D), construction instructions for a practical panel-mounted calculator using potentiometers and a null detector, and several worked example problems demonstrating its use.
