Ohm’s law is the fundamental equation used in electrical engineer and is the relationship between voltage, resistance and current. V = IR or voltage equals the current times resistance. This simple equation is easily re-arranged depending on what variables you have and which variable you need to solve for.
In electric circuits, I = V/R.

Ohm’s law states that the voltage v across a resistor is directly proportional to the current i flowing through the resistor.
