Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
It describing how voltage, current, and resistance interrelate: V = IR, where V = voltage, I = current, R = resistance.
