wheatstone bridge calculator the wheatstone bridge is a very useful circuit. when the bridge is perfectly balanced, with the same resistance on the right side and the same resistance on the left side (r1=r3, r2=rx), the voltage across the bridge is zero. however, due to small changes 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.
