Experiment Title: Wheatstone bridge Objectives: 1. To learn how to measure the coefficient of resistance of different metal wires using a Wheatstone bridge Theory: The Wheatstone bridge is a circuit used to compare an unknown resistance with a known resistance. The bridge is commonly used in control circuits. For instance, a temperature sensor View Wheatstone Bridge.pdf from MECHANICAL 101 at Tafila Technical University. THE WHEATSTONE BRIDGE B Gopalsingh Jonesboro High School PROBLEM The Wheatstone bridge is an electrical circuit used to Wheatstone Bridge Formula. Now dividing Equation 1 by Equation 2 we get, I 1 R 1 I 1 R 2 = I 2 R 3 I 2 R x R 1 R 2 = R 3 R x. This unknown resistance is determined in terms of other known resistors in the bridge. Q) Consider a bridge circuit where R 1 = 50 Ω, R 2 = 10 Ω, R 3 = 20 Ω. Wheatstone Bridge.

In these lecture notes, a brief history, the basic circuits and mathematical expressions, a side wide bridge as The apparatus for the Wheatstone bridge is a ten-turn potentiometer, a voltmeter, a standard decade. resistance box, set of resistance spools of wire, a power supply, a momentary contact switch, and a set. of connecting wires. After the apparatus is assembled correctly, using the concept that at equal. resistance, the potential is zero at the Victoria Hart W0518311 March 14, 2018 PLAB 193_03 Wheatstone Bridge Introduction The Wheatstone Bridge was invented by Samuel Hunter Christie but was made popular by Charles Wheatstone ten years later. The Wheatstone bridge in the interconnection of four resistors and can be used to determine an unknown resistance value by connecting it to a known resistor and variable resistor. Applying the Wheatstone Bridge Circuit The relationship between the applied strain ε and the relative change of the resistance of a strain gauge =⋅ε ∆ k R R "gauge factor": characteristic of the strain gauge and has to been checked experimentally: A strain gauge converts a mechanical strain into a change of an electrical resistance. 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 like a simple voltage divider). Its operation is similar to the original potentiometer. A bridge circuit in its simplest form consists of network of four resistance arms forming a closed circuit, with a dc source of current applied to two opposite junctions and a current detector connected to the other two junctions. Wheatstone‟s bridge is used for accurate measurement of resistance.
