The concept was extended to alternating current measurements by James Clerk Maxwell in and further improved by Alan Blumlein around 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. 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.

At this point, the voltage between the two midpoints B and D will be zero.
Geophone Hydrophone Microphone Seismometer. Detecting zero current with a galvanometer can be done to extremely high precision. 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 contrast with something like a simple voltage divider.

Published in “Engineering Science and Education Journal”, volume 10, no 1, Februarypages 37— In many cases, the significance of measuring the unknown resistance is related to measuring the impact wheatstonw some physical phenomenon such as force, temperature, pressure, etc. Kelvin bridge Wheatstone bridge. The Kelvin bridge was specially adapted from the Wheatstone bridge for measuring very low resistances.
