Cavendish claimed that the force between the two electrical objects gets smaller as they get further apart. If the distance between them doubled, the force would be one quarter what it was before. This was based on the inverse-square law. He explained the concept of electric potential, which was already known in Math but had been never used in electrical experiments until that day. He developed the thought of all points on a good conductor's surface have the same potential energy beside a common reference point. Because of no possibility to measure electric current, he used his body as a machine which measures strength of electric current. All Cavendish's explorations in his notebook was found and confirmed by James Clerk Maxwell.
