• Admittance element — An element, circuit, or quantity characterized by admittance; a component or medium capable of allowing the passage of alternating electrical current or energy flux in a physical system. As a derived quantity, it is the inverse of impedance and measures the ease with which an electric circuit conducts current, heavily used in power engineering calculations and network design.
• Admittance-based — Possessing the characteristics of admittance; facilitating the conduction of alternating electrical current or energy flux transfer within a circuit. It represents the feminine form of the adjective 'admitant', specifically used to describe physical quantities, mathematical matrices, or structural components capable of reducing the overall impedance in a complex technical system.
• Admittance meter — An electronic measuring instrument used for the direct or indirect determination of the electrical admittance of a circuit, device, or semiconductor material; a laboratory tool structurally designed to evaluate both the active component (conductance) and the reactive component (susceptance) under high-frequency alternating current conditions.
• Wind turbine — A complex technical installation (wind turbine) consisting of a bladed rotor, a speed multiplier, and an electrical generator, structurally designed to capture the kinetic energy of the wind and transform it directly into useful electrical energy. It represents the fundamental pillar of modern wind power plants destined for clean and renewable energy production.
• Alnico — A ferromagnetic alloy with superior magnetic properties, made from a structural composition of iron mixed with aluminum (Al), nickel (Ni), and cobalt (Co), to which small percentages of copper or titanium may be added. This structural material is widely used in manufacturing high-power permanent magnets for audio loudspeakers, electric motors, industrial sensors, and microphones.
• Alternator — A rotating electrical machine that transforms mechanical energy supplied by an internal combustion engine or another source of motion into electrical energy in the form of alternating current; an essential component of the charging system in modern vehicles.
• 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.
• Amperage — A term used in common or informal language to designate the intensity of an electric current, expressed in amperes. Although theoretical physics and official metrology prefer the phrase 'electric current intensity', the word is standardized in industry and practice to indicate the load capacity of fuses, circuits, or chargers.
• 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.
• Amplidyne — A special direct current electrical generator with armature reaction, utilized as an electromagnetic power amplifier in automatic regulation and electrical drive systems. This device uses the magnetic flux of the short-circuit armature current to achieve an extremely high amplification factor, allowing the control of large output powers using very small electrical command signals.
• Analogic — Pertaining to analogy, based on analogy, proceeding by analogy, or representing physical quantities via continuous variations. In electronics and telecommunications, it describes equipment or a signal whose values vary fluidly and uninterruptedly over time (such as radio waves or vinyl records), in direct opposition to digital systems that use discrete binary values. In linguistics, it refers to word transformations based on pre-existing morphological models.
• Anti-induction — A technical procedure, structural measure, or device used to reduce or completely cancel the disruptive effects of parasitic electromagnetic or electrostatic induction between neighboring electrical circuits or telecommunication lines. In an industrial sense, it is achieved through metallic shielding, wire twisting in cables, or the use of special compensating coils.
• Asynchronous — Not occurring at the same time as another phenomenon or not coordinated by a common clock signal; non-synchronized. In computer science and programming, it describes the structural running of operations in the background, allowing code execution without blocking the main thread, thus optimizing system resources.
• Self-excitation — The act of self-exciting and its result; the process of magnetizing an electric generator using the current generated by itself, or the autonomous generation of a nerve impulse or biological alert state without external stimulants.
• Self-excited — Regarding machines, generators, or electrical systems: self-excited; producing its own excitation current required to create its magnetic field without an external power source. Broadly or figuratively, it describes a system, circuit, or state that stimulates, maintains, or amplifies itself through its own internal mechanisms or residual reactions.
• 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.
