The Wheatstone bridge was invented by Samuel Hunter Christie (sometimes spelled "Christy") in 1833 and improved and popularized by Sir Charles Wheatstone in 1843. The goal of this lab is to use a virtual Wheatstone bridge to measure a set of unknow resistors made by the same material, and finally get the resistivity value of this material.
