WebThe principle of the circuit is that if three resistances are known, and the current in the cross branch is zero, the fourth resistance can be calculated. The measurement can be made very accurately since zero current can be detected with extremely high accuracy using a sufficiently sensitive galvanometer. WebStrain gages are configured in Wheatstone bridge circuits to detect small changes in resistance. The Wheatstone bridge is the electrical equivalent of two parallel voltage …
WebNov 5, 2024 · The Wheatstone bridge consists of two pairs of resistors connected in a series-parallel combination, as shown in the image above. Resistances R 1 R_1 R 1 and R 2 R_2 R 2 are in series, similar to the resistances R 3 R_3 R 3 and R x R_x R x .These two resistance arms are parallel to each other. WebThe unknown resistance, R x, is given by:. History: The Wheatstone bridge was invented by Samuel Hunter Christie in 1833 and improved and popularized by Sir Charles Wheatstone in 1843. It is used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component.
At the point of balance, both the voltage and the current between the two midpoints (B and D) are zero. Therefore, , , , and: First, Kirchhoff's first law is used to find the currents in junctions B and D: Then, Kirchhoff's second law is used for finding the voltage in the loops ABDA and BCDB:
