Whose law governs electric current?

In 1827 Georg Ohm published the relationship now known as Ohm law, which states that the current flowing through a conductor is proportional to the voltage across it and inversely proportional to its resistance. In simple terms, more voltage pushes more current, while more resistance reduces it. This straightforward rule became one of the most fundamental principles in the study and design of electrical circuits. At first Ohm work was poorly received, but it later earned wide recognition. The unit of electrical resistance, the ohm, is named after him.
