Who proved ohms law to be true?

Answer 1

Its not so much the proof of the law, as it is the acceptance of the terminology created by the law.

Ohm's law states that the current through a conductor is directly proportional to the voltage across the conductor and inversely proportional to the resistance of that conductor. In mathematical terms this is ...

I = V/R

... where I is current in amperes, V is voltage in volts, and R is resistance in ohms.

This is not Georg Ohm's original equation, but rather a modern interpretation of the wording of the law.

The impact of Ohm's law is in the definition of the ohm. Rewrite the above equation as R = V/I, and you see immediately that the ohm is simply volts per ampere. Take it deeper, realizing that the volt is joules per coulomb and that the ampere is coulombs per second, and you discover that the ohm is joules-seconds per coulomb squared. How would you like to use that term, instead of the elegantly more simple term ohm?

In summary, then, ohm's law sets the relationship between what we call the volt, the ampere, and the ohm.

Answer 2

Ohm's law is named after the German physicist Georg Ohm who discovered the law and published it in 1827.

This law states that the flow of current through a resistor is proportional to the voltage applied. It took years before this simple relationship was accepted by the scientific community of the time.
