Calculate R4 resistance for a balanced bridge, or. 2. Calculate the cross-bridge voltage V b. To calculate R4, select "Resistance of R4 for balanced bridge" and add the values for R1, R2, and R3 as directed. To calculate the cross-bridge voltage, select "Voltage across the bridge V b " and input the values for R1 ...
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: 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.
