WebMar 10, 2024 · As shown in the formula above, the Wheatstone Bridge circuit has four resistance elements, or arms: R1, R2, R3, and R4. These arms can be replaced by one, two, or four strain gages, or active arms. A bridge circuit with one strain gage and three fixed resistors is called a quarter-bridge, since one-fourth of the four arms are strain gages. http://api.3m.com/wheatstone+bridge+experiment+theory
