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. Some of the modifications are:.
The equations for this are:. Schering Bridge Wien bridge. Jembwtan 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.

Wheatstone bridge – Wikipedia
The Kelvin bridge was specially adapted from the Wheatstone bridge for measuring very low resistances. 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 whextstone is not suitable. 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 explosimeter.
Detecting zero current with a jembaatan can be done to extremely high precision.
The desired value of R x is now known to be given as:. First, Kirchhoff’s first law is used to find wheattstone currents in junctions B and D:. 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.
At this point, the voltage between the two midpoints B and D will be zero.

Published in “Engineering Science and Education Journal”, volume 10, no 1, Februarypages 37— The concept was extended to alternating current measurements by James Clerk Maxwell in and further improved by Alan Blumlein around Electrical meters Bridge circuits Measuring instruments English inventions Impedance measurements. Diode bridge H bridge. The primary benefit of the circuit is its ability to provide extremely accurate measurements in contrast with something like a simple voltage divider.
Geophone Hydrophone Microphone Seismometer. This page was last edited on 8 Novemberat To do so, one has to work out the voltage from each potential divider and subtract one from the other.
Kelvin bridge Wheatstone bridge. The Wheatstone bridge illustrates the concept of a difference measurement, which can be extremely accurate.
