Ohm's law

Ohm's law applies to electrical circuits: the current between two points is directly proportional to
the potencial difference and inversely proportional to the resistence.
The equation that describes this relationship is:

V=IR (V=I·R)

Where V is the intensity between two points, in volts (V), I is the current or power, in amperes (A) and R is the resistence of the circuit.

The law was named after the physicist Georg Ohm (what a surname!) in 1827. It's one of the most equation used by electronic engineers and computers in the circuit analysis.

What can I say...? There's nothing I can say more... yes, it's obsolete!
