What is Wheatstone Bridge?

The Wheatstone bridge was invented by Samuel Hunter Christie in 1833 and improved and popularized by Sir Charles Watson in 1843. One of the early applications of Paul Whetstone was for soil analysis and comparison.

Wheatstone bridge demonstrates the concept of difference measurement, which can be very accurate. Variations on the Wheatstone bridge can be used to measure capacitance, inductance, impedance, and other quantities such as the amount of combustible gases in a sample with an Explosometer. The Kelvin bridge is specially adapted from the Wheatstone bridge for measuring very low resistances. In many cases, the importance of measuring the unknown resistance is related to the measurement of the effect of some physical phenomena (such as force, temperature, pressure, etc.), thus it is possible to use Paul Watson in the indirect measurement of those elements.
This property is used in the load cell to measure the amount of force.
