ohm Definition
the standard unit of electrical resistance in the International System of Units (SI), equal to the resistance of a circuit in which an electromotive force of one volt produces a current of one ampere.
Using ohm: Examples
Take a moment to familiarize yourself with how "ohm" can be used in various situations through the following examples!
Example
The resistance of this circuit is 5 ohms.
Example
The light bulb burned out because it drew too much current for the 60-watt power supply and the 120-volt line, resulting in a current of 0.5 amperes and a resistance of 240 ohms.
Origins of ohm
named after Georg Simon Ohm, a German physicist
Summary: ohm in Brief
'Ohm' [oʊm] is the standard unit of electrical resistance in the International System of Units (SI). It measures the resistance of a circuit in which an electromotive force of one volt produces a current of one ampere. For example, 'The resistance of this circuit is 5 ohms.'
