To do so, one has to work out the voltage from each potential divider and subtract one from the other.
Detecting zero current with a galvanometer can be done to extremely high precision. A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuitone leg of which includes the unknown component.
The equations for this are:. Geophone Hydrophone Microphone Seismometer. The Kelvin bridge was wheststone adapted from the Wheatstone bridge for measuring very low resistances.

From Wikipedia, the free encyclopedia.
The concept was extended to alternating current measurements by James Clerk Maxwell in and further improved by Alan Blumlein around Variations on the Wheatstone bridge can be used to measure capacitanceinductanceimpedance and other quantities, such as the amount of combustible gases in a sample, with an wheatstond. First, Kirchhoff’s first law is used to find the currents in junctions B and D:.
The primary benefit of the circuit is its ability to provide extremely accurate measurements in jdmbatan with something like a simple voltage divider. In other projects Wikimedia Commons.
Some of the modifications are:. Kelvin bridge Wheatstone bridge. On the other hand, if the resistance of the galvanometer is high enough that I G is negligible, it is possible to compute R x from the three other resistor values and the supply voltage V Sor the supply voltage from all four resistor values.
This setup is frequently used in strain gauge and resistance thermometer measurements, as it is usually faster to read a voltage level off a meter than to adjust a resistance to zero the voltage.

In many cases, the significance of measuring the unknown resistance is related to measuring the impact of some physical phenomenon such as force, temperature, pressure, etc.
The Wheatstone bridge is the fundamental bridge, but there are other modifications that can be made to measure various kinds of resistances when the fundamental Wheatstone bridge is not suitable. The desired value of R x is now known to be whetastone as:. Published in “Engineering Science and Education Journal”, volume 10, no 1, Februarypages 37— Schering Bridge Wien bridge. Diode bridge H bridge. The Wheatstone bridge illustrates the concept of a difference measurement, which can be extremely accurate.

At this point, the voltage between the two midpoints B and D will be zero. Views Read Edit View history.
One of the Wheatstone bridge’s initial uses was for the purpose of soils analysis and comparison. Retrieved from ” https:
