  2. In 1827, German physicist Georg Simon Ohm (1787–1854) found out the relationship between the current I, flowing in a metallic wire and the potential difference across its terminals. The potential difference, V, across the ends of a given metallic wire in an electric circuit is directly proportional to the current flowing through it.

    This popular law of physics is said to be first discovered by English physicist Henry Cavendish who never published his scientific findings on electric current. Later on, when Ohm did his own research on the relation between voltage and current, he came across similar discoveries and published the law under his name.

    Ohm demonstrated that there are no “perfect” electrical conductors through a series of experiments in 1825. Every conductor he tested offered some level of resistance. These experiments led to Ohm’s law.

    Using a compass needle placed near a wire as a measure of electrical current (ammeters had not yet been invented), Ohm discovered that, for a given wire, the current through the wire is proportional to the strength of the battery (we would say the voltage), but that for other wires, the current might be different for the same voltage.
