Definition of ohm's law in English English dictionary
Ohm's observation that the direct current flowing in an electrical circuit consisting only of resistances is directly proportional to the voltage applied
The law stating that the direct current flowing in a conductor is directly proportional to the potential difference between its ends. It is usually formulated as V = IR, where V is the potential difference, or voltage, I is the current, and R is the resistance of the conductor. Relationship between the potential difference (voltage), electric current, and resistance in an electric circuit. In 1827 Georg Simon Ohm discovered that at constant temperature, the current I in a circuit is directly proportional to the potential difference V, and inversely proportional to the resistance R, or I = V/R. Resistance is generally measured in ohms (). Ohm's law may also be expressed in terms of the electromotive force E of an electric energy source, such as a battery, or E = IR. In an alternating-current circuit, when the combination of resistance and reactance, called impedance Z, is constant, Ohm's law is applicable and V/I = Z
force of a direct current is proportional to the potential difference and inversely proportional to the resistance of the circuit (Electricity)
electric current is directly proportional to voltage and inversely proportional to resistance; I = E/R
