#ampermetru
- Ampere — The fundamental base unit in the International System of Units (SI) for electrical current intensity, defined by taking the fixed numerical value of the elementary electron charge. One ampere (symbol: A) represents the flow of electric charge equivalent to one coulomb per second passing through a cross-section of an electrical conductor.
- Ammeter — An apparatus or measuring instrument used to determine the intensity of an electric current flowing through a circuit, expressed in amperes or its subdivisions (milliamperes, microamperes). To perform a correct measurement, the device must be connected in series within the analyzed electrical circuit and possesses an extremely low internal resistance to avoid altering the initial electrical parameters.
- Avometer — A portable measuring instrument, analog or digital, utilized in electrical engineering and electronics to determine the numerical values of the main electrical quantities within a structural circuit. Its name is an acronym formed from the fundamental measurement units it records: Amperes (current intensity), Volts (electrical voltage), and Ohms (electrical resistance); multimeter.
