Ohm's Law

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. This article is about the law related to electricity. For other uses, see Ohm''s acoustic law. V, I, and R, the parameters of Ohm''s law. In electrical circuits, Ohm''s law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them. The law was named after the German physicist Georg Ohm, who, in a treatise published in 1827, described measurements of applied voltage and current through simple electrical circuits containing various lengths of wire. He presented a slightly more complex equation than the one above (see History section below) to explain his experimental results. The above equation is the modern form of Ohm''s law.
