What are the 3 forms of Ohm's law?

There are three forms of Ohm’s law that relate to voltage, current, and resistance. For a constant flow of current, the current is given by the ratio of voltage across terminals to the resistance of the resistor.

I = V/R

Ohm’s law can also be written as

R = V/I

V = IR

I is the current
V is the voltage
R is the resistance
