The Ohm's law states that at constant temperature the current flowing through a conductor is directly proportional to the potential difference across its ends . This means that I proportional to V. Two equate this we need to add a constant. This we get V=R*I . But why can't we write the same equation by adding a constant on the other side as I=R*V . How do we know which side to add the constant and how?
