Probably the most important mathematical relationship between voltage current and resistance in electricity is something called Ohm s Law. In this algebraic expression voltage E is equal to current I multiplied by resistance R. Ohm expressed his discovery in the form of a simple equation describing how voltage current and resistance interrelate.
This reformulation of Ohms law is due to Gustav Kirchhoff.
A man named George Ohm published this formula in 1827 based on his experiments with electricity. J s E displaystyle mathbf J sigma mathbf E where J is the current density at a given location in a resistive material E is the electric field at that location and s sigma is a material-dependent parameter called the conductivity. What is Ohms Law formula equation triangle Ohms Law is one of the most fundamental of laws for electrical theory. What mathematical equation is used where I and R are known and E is to be determined.
