Determine the unknown resistance (Rx) in a balanced Wheatstone Bridge circuit. Widely used in precision measurements and strain gauge sensor applications.
A bridge is balanced when the voltage difference between the two midpoints is zero, meaning the ratio of resistances in both legs is equal.
It is primarily used for measuring very small changes in resistance, such as those in strain gauges, load cells, and temperature sensors.
Rx = (R2/R1) * R3
