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 … WebThe Wheatstone Bridge is an instrument designed for measuring an unknown resistance by comparing it with a known, or standard, resistor. In the schematic diagram in section IV, R1 is an unknown resistor whose value is to be determined. Three known resistors are required, as well as a galvanometer and a cell (battery).
WebJan 1, 2024 · You need to apply the delta-wye transformation back and forth (combining resistors when you can) until you have simplified the circuit to a single resistance between A and B. The Wheatstone Bridge method is used to determine the value of an unknown resistor. It is not a method for practical use in solving circuits like this. WebWheatstone bridge can be used to determine the value of an unknown resistance in the arrangement of four resistances among which three are known resistances. It was invented by British physicist Charles Wheatstone in 1843. The arrangement for Wheatstone’s bridge is shown in the figure.
