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.
Georg Ohm
Ohm
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 law of inertia, also known as Newton's First Law of Motion, was discovered by Sir Isaac Newton in the 17th century. He formally published this law in his book "Mathematical Principles of Natural Philosophy" in 1687.
The mathematical equation describing the relationship between electric current, voltage, and resistance was discovered by George Ohm in the 1820s. Ohm's Law states that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R), expressed as I = V/R.
Assuming you mean an electrical current, you can use Ohm's Law to determine the current: V = IR, or I = V/R.
Ohms Law
Albert Einstein did not discover the third law of motion. This law was formulated by Sir Isaac Newton in his publication "Mathematical Principles of Natural Philosophy" in 1687.
