Ohm - Wikipedia
WEBThe ohm (symbol: Ω, the uppercase Greek letter omega) is the unit of electrical resistance in the International System of Units (SI). It is named after German physicist Georg Ohm .
Ohm | Electricity, Resistance & Voltage | Britannica
WEBohm, abbreviation Ω, unit of electrical resistance in the metre-kilogram-second system, named in honour of the 19th-century German physicist Georg Simon Ohm. It is equal to the resistance of a circuit in which a potential difference of one volt produces a current of one ampere (1Ω = 1 V / A ); or, the resistance in which one watt of power is ...
What is an ohm and what does it measure? – TechTarget Definition
WEBThe ohm is a measurement of resistance between two points of a conductor when a constant potential difference of one volt (V) is applied to those points and a current of one ampere is produced. In simpler terms, it's the equivalent of one volt per one ampere (V/A).
Ohm Definition & Meaning - Merriam-Webster
WEBThe meaning of OHM is the practical meter-kilogram-second unit of electric resistance equal to the resistance of a circuit in which a potential difference of one volt produces a current of one ampere.
What is Ohm (Ω)? Unit of Electrical Resistance and Impedance
WEBThe unit of Ohm denoted by the symbol of Ω (the Greek letter omega) is used to measure the resistance between two points in a circuit or conductor. An Ohm is defined as: One ohm is equal to the resistance of a conductor that allows a current of one ampere to flow through it when a voltage of one volt is applied across its terminals.
Georg Ohm | Biography & Facts | Britannica
WEBMar 29, 2024 · electricity. Georg Ohm (born March 16, 1789, Erlangen, Bavaria [Germany]—died July 6, 1854, Munich) was a German physicist who discovered the law, named after him, which states that the current flow through a conductor is directly proportional to the potential difference (voltage) and inversely proportional to the …
OHM Definition & Meaning | Dictionary.com
WEBOhm definition: the standard unit of electrical resistance in the International System of Units (SI), formally defined to be the electrical resistance between two points of a conductor when a constant potential difference applied between these points produces in this conductor a current of one ampere.
Ohm’s law | Physics, Electric Current, Voltage | Britannica
WEBOhm’s law, description of the relationship between current, voltage, and resistance. The amount of steady current through a large number of materials is directly proportional to the potential difference, or voltage, across the materials. Thus, if the voltage V (in units of volts) between two ends

Introduction to circuits and Ohm's law (video) | Khan Academy
WEBAbout. Transcript. Ohm’s Law is V = IR, where V = voltage, I = current, and R = resistance. Ohm’s Law allows you to determine characteristics of a circuit, such as how much current is flowing through it, if you know the voltage of the battery in the circuit and how much resistance is in the circuit.
