Wheatstone Bridge Calculator

What is a Wheatstone Bridge Calculator?

A Wheatstone Bridge Calculator is a tool used to calculate unknown resistances using the Wheatstone Bridge circuit. The Wheatstone Bridge is a circuit that allows precise measurement of an unknown electrical resistance by balancing two legs of a bridge circuit. It consists of four resistors arranged in a diamond shape with a voltage source applied across the bridge, and a galvanometer (a device for measuring current) in the middle.

By adjusting known resistances in the circuit and achieving a balanced condition (where the galvanometer shows zero current), the value of the unknown resistor can be calculated.
