Ohm - Wikipedia
The 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.
What are amps, watts, volts and ohms? | HowStuffWorks
2022年10月3日 · There is a basic equation in electrical engineering that states how the three terms relate. It says that the current is equal to the voltage divided by the resistance or I = V/R. This is known as Ohm's law (named after our friend Georg Simon Ohm).
What is an ohm and what does it measure? – TechTarget Definition
The ohm is the standard unit of electrical resistance in the International System of Units (SI). It's one of the derived units defined in the SI standard, which means it's based directly or indirectly on the standard's fixed constants.
Ohm Definition & Meaning - Merriam-Webster
The 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
What is Ohm Ω? Ohm is a unit of electrical resistance, named after Georg Simon Ohm, a German physicist who discovered Ohm’s Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature and other physical conditions remain constant.
