Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. State Ohm's law ? Thus, this law of Ohm can be expressed with the equation or formula, V = IR Thus, the derivation of Ohm’s law is done. Ohm’s law is only valid for Ohmic material such as metals. So we have seen that this law of Ohm can be expressed with the formula or equation, V = IR where V is the potential difference across the metallic element and I is the current flowing through the element. The above equation is the modern form of Ohm's law. Get the answers you need, now! How can it be experimentally verified ?
