The Wheatstone Bridge formula is used to calculate the value of an unknown resistor in a balanced bridge circuit.

• The formula is: R1/R2 = R3/Rx

• R1, R2, and R3 are known resistors, and Rx is the unknown resistor

• The bridge is considered balanced when the ratio of R1 to R2 is equal to the ratio of R3 to Rx

• The formula can be rearranged to solve for Rx: Rx = (R2 * R3) / R1
