Wheatstone Bridge Calculator The Wheatstone bridge is a very useful circuit. When the bridge is perfectly balanced, with the same resistance on the right and the same resistance on the left (R1=R3, and R2=RX), the voltage across the bridge is zero. However, due to a small change in resistance, the bridge becomes unbalanced and a voltage difference occurs. Wheatstone bridge applications such as strain gauges, pressure gauges, sensors and various other devices.
