#circuit
- 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.
- Gathering — The feminine singular or plural form of the substantivized adjective adunător, describing a person, animal, device, or action that gathers, collects, or accumulates scattered elements. In anthropology and history, it defines primitive communities based on the collection of natural resources. In electronics and cybernetics, it denotes a logical circuit or scheme that performs the operation of adding binary data or signals.
- Air vent — A technical device, component, or valve installed in a heating, hydraulic, or braking system for the purpose of automatically or manually eliminating air or gas bubbles trapped inside the circuits. It also designates any small opening or grille structurally designed to ensure passive ventilation of an enclosure.
- AHPL — Acronym for 'A Hardware Programming Language', representing an early hardware description language (HDL) developed based on APL syntax in the 1970s by Hill and Peterson. It is used in academia and digital system design for the structural and behavioral modeling of register-transfer level (RTL) actions and for the precise simulation of digital microarchitectures.
- Alienable — Capable of being alienated, transferred, sold, or legally assigned from one patrimony to another. In civil law, this adjective describes the legal status of most assets within the private commercial circuit, indicating that the owner possesses the full prerogative of legal disposition over them, as opposed to inalienable assets (such as public state property).
- Alienability — The quality or legal character of being alienable; the lawful capability of an asset, right, or property title to be validly transferred, sold, donated, or assigned from one patrimony to another. This structural characteristic constitutes the baseline rule of the private civil circuit, fully guaranteeing the freedom of disposition for economic rights holders.
- Priming — The phenomenon, action, or initial phase of triggering, priming, or starting up a device, apparatus, electrical circuit, or technical system. In electrical engineering, it represents the establishment of an electric arc or the initialization of an electrical discharge in a gas, while in mechanics, it indicates the start of a fluid flow or fuel mixture ignition.
- Priming — The act of priming and its result; the process of preparing, initiating, triggering, or starting up a technical system, an electrical circuit, or a hydraulic pump. In construction, it represents the application of a primer coat to seal pores, while in molecular biology, it defines the annealing of oligonucleotides (primers) onto the template DNA strand to begin synthesis.
- 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.
- Ampere-hour — A unit of measurement for electric charge or the energy storage capacity of an accumulator or battery, represented by the symbol Ah. One ampere-hour corresponds to the total electric charge transferred by a steady current of one ampere flowing continuously for one hour, being mathematically equivalent to 3,600 coulombs.
- 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.
- Ampere-hour meter — An instrument or measuring apparatus designed to determine and integrate the total quantity of electricity flowing through an electrical circuit over a timeframe, expressed in ampere-hours (Ah). This device functions as a time-integrator of the electrical current intensity, being primarily utilized for monitoring the state of charge and discharge of industrial accumulator banks.
- Amplifier — An apparatus, electronic device, or technical assembly that increases the power, voltage, or intensity of an electrical, acoustic, or light signal received at the input, utilizing energy from an external source; as an adjective, it describes any element or factor that boosts or intensifies an effect, a state, or a physical or social phenomenon.
- Stereo receiver — A complex high-fidelity electronic apparatus that structurally combines a radio receiver (tuner) and an audio power amplifier within a single chassis. This device allows selecting, receiving, and decoding radio stations broadcast over ultra-short or medium waves, while simultaneously ensuring signal amplification and its efficient distribution to a modular speaker system.
- To engage — To establish an electrical connection by closing a circuit using a switch, relay, contactor, or circuit breaker; to put an automated system or apparatus into operation. Broadly, the action describes the automatic or manual triggering of a switching mechanism, being the opposite of the term 'to trip' or 'to uncouple'.
- Engagement — The act of engaging or closing an electrical circuit; the technical operation of making a circuit or coupling a mechanism via a switching apparatus. In power systems, the process represents the restoration of current flow within a network, which can be performed manually by an operator or automatically by specialized relays following the restoration of nominal parameters.
- Engaged — Having the electrical circuit closed; coupled, connected, or put into operation via a switching device. The term describes the stable operational state of a switch, relay, or contactor whose internal contacts are firmly touching, allowing the flow of electrical current to consumers.
