Are you talking about Ohm's Law. Voltage = (Current) x (Resistance). Georg Ohm
There is not one, but several, laws related to electrical current. None of them are called "mathematical laws".If you mean Ohm's Law, that one was discovered by a certain Mr. Ohm.
Georg Ohm
A simple law is the commutative addition law.

a formula
A formula is defined as a mathematical expression of a natural law. A formula is a combination of numbers and symbols used to describe how something works.

Current = voltage/resistance
Ohm's most important discovery was in 1826 when he discovered the mathematical law of electric current called Ohm's law.
The mathematical form of Ohms law is I=V divided by R. I is current, V is voltage while R is the resistance.
Ohm's Law
Ohm's law is the basic answer. Voltage = Current * Resistance is ohms law. In order to find current divide voltage by Resistance V/R=I where I is current.
The ampere wasn't really discovered. It is the word given to the unit of electrical current. It is named after André-Marie Ampère (1775-1836), a French physicist that found the science of electromagnetism. In 1820, Ampère performed a series of experiments. These experiments led him to formulate the law of electromagnetism, named after him, Ampère's law, that mathematically shows the magnetic force between two electrical currents.
Assuming you mean an electrical current, you can use Ohm's Law to determine the current: V = IR, or I = V/R.
Ohms Law
you can make your own mathematical law, but it should be very similar and related to the original mathematical law. also there is an another issue, sometimes your own mathematical law will not work, so it is very important and better to use the original mathematical law to avoid mistakes and to get the correct answer.
Ohm's Law Voltage = Current x Resistance. So for a fixed voltage as R decreases then current increases proportionally.
