The ampere (/ ˈ æ m p ɛər / AM-pair, US: / ˈ æ m p ɪər / AM-peer; symbol: A), often shortened to amp, is the unit of electric current in the International System of Units (SI). One ampere is equal to 1 coulomb (C) moving past a point per second.
Ampere is the unit of electric current that measures the flow of charge per second. Learn how to convert ampere to other units, how to calculate ampere with watts and volts, and what are the types of ammeters.
The meaning of AMPERE is the practical meter-kilogram-second unit of electric current that is equivalent to a flow of one coulomb per second or to the steady current produced by one volt applied across a resistance of one ohm.
An ampere is the standard unit of measurement for the strength of an electric current. Learn how to use the word ampere in physics and other contexts with Cambridge Dictionary.
Ampere is a unit of electric current in the International System of Units (SI), named after French physicist André-Marie Ampère. It represents a flow of one coulomb of electricity per second and is related to the elementary charge and the volt.
The SI unit used to measure electric current. Electric current through any given cross-section (such as a cross-section of a wire) may be measured as the amount of electrical charge moving through that cross-section in one second.
Ampere is the unit of electric current that measures the flow of electrons in a circuit. Learn the definition, types, derivation and examples of ampere and how to measure it with ammeters.
