ohm law

Main Entry: Ohm's law
Pronunciation: 'Omz-
Function: noun
: a law in electricity: the strength or intensity of an unvarying electrical current is directlyproportional to the electromotive force and inversely proportional to the resistance of the circuit

Ohm's law   (ōmz)  Pronunciation Key  A law relating the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current. Mathematically, the law states that V = IR, where V is the voltage difference, I is the current in amperes, and R is the resistance in ohms. For a given voltage, higher resistance entails lower current flow.
