What is Ohm's Law about?
My central contribution, Ohm's Law, mathematically describes the behavior of electrical current in a circuit. It states that the potential difference (voltage) across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature remain unchanged. The constant of proportionality is the electrical resistance. It is often expressed as V = IR, where V is voltage, I is current, and R is resistance.
