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 to explain his experimental results. The above equation is the modern form of Ohm's law.

Law that states that, for many materials over a wide range of conditions, the current flowing in a conductor maintained at constant temperature is directly proportional to the potential difference (voltage) between its ends

In 1827 Georg Simon Ohm discovered some laws relating to the strength of a current in a wire. Ohm found that electricity acts like water in a pipe. Source: www.code-electrical.com/ohmslaw.html

Ohm didn't 'invent' the law, he discovered it or, rather, he discovered the relationships involved through a series of practical experiments. When you think about it, this was quite an achievement because he had to design and build his measuring instruments (except, perhaps, for a basic tangent galvanometer, there were no standard instruments or even voltage supplies!) and there were no such things as 'volts' or 'amperes' (standard measurements didn't exist in those days!). So, he had to conduct his experiments in an age when there was no measuring instruments or units of measurement!

In 1827 a German Physicist, Georg Simon Ohm, discovered that the electric current in metallic conductors was proportional to the voltage drop across the conductor. That is, if the voltage is doubled, the current is doubled. If the voltage is tripled, the current tripled.

This discovery has become known as Ohm's Law!!

All I know is who and when it was made but never where. It would probably come from Dr. Ohm himself.

Ohm's Law: Voltage is current times resistance.

Answer

Essentially, Ohm's Law states that, for some conductors, the ratio of voltage to current is constant for variations in voltage. Conductors and other devices that obey Ohm's Law are called 'linear' or 'ohmic' devices; but there are many more devices that do not obey Ohm's Law, and these are called 'non-linear' or 'non-ohmic'. So we can say that Ohm's Law is by no means a 'universal law', as it only applies to some materials. For example, it does not apply to tungsten lamps, whose ratio of voltage to current changes significantly if the applied voltage is increased, and it does not apply to many electronic components, such as diodes.

The ratio of voltage to current is, of course, resistance. And this ratio will always tell you what the resistance happens to be at a particular ratio of voltage to current. So, using tungsten as an example, you can find out what its resistance happens to be for any given voltage by using the ratio of voltage to current at that particular voltage -and you will find that, as the applied voltage increases, so does the resistance of the tungsten.
