## 1827: Mathematical Analysis of the Electric Circuit

Innovation: Mathematical Analysis of the Electric Circuit

Location: Erlangen, Germany

Year: 1827

By: Georg Ohm

With the publication of The Galvanic Circuit Investigated Mathematically written by Georg Ohm in 1827, Ohm’s Law, which is used to understand electrical circuits, was established. In this work Ohm set forth to explain that the electromotive force anywhere in a circuit is the product of the strength of the current and the resistance in that part of the circuit, V=IR. At the time his work was published, most approaches to physics were non-mathematical; therefore, his work set the stage for electricity that can be explained in mathematical terms and thus making it easier for non-physicists to understand the flow of electricity. Ohm’s mathematical analysis of electric circuits is what most electricians and engineers rely on to understand the flow of electricity through houses and appliances and the proper method to account for electrical flow.
