WebWheatstone Bridge. Wheatstone bridge is an electrical circuit which is used to calculate unknown resistance. It was also used to calibrate measuring instruments such as … WebThe following unbalanced Wheatstone bridge is constructed. Calculate the output voltage across points C and D and the value of resistor R4 required to balance the bridge circuit. Transcribed Image Text: R: 1800 R3 4802 10Vi Vout D R2 1202 R4 1602. A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component. The primary benefit of the circuit is its ability to provide extremely accurate measurements (in contrast with something … See more In the figure, Rx is the fixed, yet unknown, resistance to be measured. R1, R2, and R3 are resistors of known resistance and the resistance of R2 is adjustable. The resistance R2 is adjusted until the bridge is … See more The Wheatstone bridge illustrates the concept of a difference measurement, which can be extremely accurate.
