Problems on wheatstone bridge
WebbThe four arms or branches of the bridge circuit are formed by the resistances R 1 to R 4.The corner points 2 and 3 of the bridge designate the connections for the bridge … WebbWheatstone bridge offset. For example, with 0.1% tolerance for each one of the individual elements and a 5-V excitation voltage, the differential offset can be as high as 5 mV. If a gain of 400 is required to achieve the desired bridge sensitivity, the offset becomes ±2 V at the amplifier output.
