    Use the Wheatstone Bridge Calculator to find unknown resistance using R1, R2, and R3. Perfect for lab work, sensor measurements, and electrical circuit analysis. A Wheatstone Bridge Calculator is a tool to find the value of an unknown resistor in a balanced bridge circuit based on three known resistances. It applies the simple fan equation Rx = (R3 R2)/R1to find the value that is missing, which is applicable in sensors and electrical analysis.

    What is the Wheatstone Bridge?

    The Wheatstone Bridge Calculator is an efficient yet straightforward decision maker to calculate the value of a resistor that is not known (Rₓ) in a bridge network. The Wheatstone bridge, widely applied in electrical laboratories (as part of circuit analysis) and electrical sensors (such as strain gauges), is based upon the principle of balancing a circuit between both legs of the bridge. To a ratio of resistances, but when the bridge is balanced (i.e., the voltage across the central galvanometer is zero), then:

    (R1 / R2) = (R3 / Rx)

    Rearranging this formula gives:

    Rx = (R3 × R2) / R1

    wheatstone bridge formula tool:

    You can enter the known values of R1, R2, and R3, and then this calculates the unknown resistance (Rx). It is time-saving and accurate; thus, it is suitable for students, engineers, and other technicians using analog sensors, resistive networks, or diagnostics within their circuits. The calculator has the assumption that the bridge is balanced with temperature or lead resistance disregarded. Make field or experimental fast calculation verification.
