Definitions for "Ohm's Law"
This is the electrical circuit law that states that V=IR. That is, the electric potential (in volts) equals the current (in amperes) times the resistance (in ohms).
The basic relationship between current, voltage, and resistance. Ohm's law states that voltage = current x resistance, current = voltage/resistance, and resistance = voltage/current.
The formula established by Georg Simon Ohm (1787-1854) relating voltage, current and resistance in any electrical system and usually expressed as E = IR where E is voltage, I is current and R is resistance.
