capacitor
noun
A capacitor is an electronic component whose predominant property is its electrical capacity.
Example: In principle, there are always two electrodes with an inserted dielectric, but depending on the details of the capacitor design, under different conditions their undesirable (parasitic) properties (eg series resistance, leakage, inductance, temperature dependences, changes in properties over time, capacitance nonlinearity) ( voltage dependence), etc.).
sk: kondenzátor
clamp
noun
Conductive part of electrical equipment, sources, devices, etc. designed for detachable connection of one or more conductors.
Example: 3-pole electrical clamp.
sk: svorka
coil
noun
The coil is a passive electrical element, which is a real representation of inductance in an electrical circuit.
Example: Technically, the coil consists of an insulated conductor wound on a non-conductive support frame. The winding can be single-layer or multi-layer. The wound conductor can be structurally or self-supporting - without a frame, the coil threads are glued to each other. The properties of the coil are significantly affected by the presence of the magnetic core (its permeability) (a coil without a core is also called an air coil).
sk: cievka
converter
noun
A digital-to-analog converter is an electronic device for converting a digital signal to an analog signal.
Example: An example is a sound card that receives digital information from a processor (such as a decoded MPEG song) and transmits it to an speaker through an amplifier and equalizer using a digital-to-analog converter.
sk: prevodník
Didactics
noun
Didactics is a pedagogical science dealing with teaching.
Example: Didactics is a pedagogical science dealing with teaching.
sk: didaktika
driver
noun
An electric conductor from the point of view of physics is a material (substance) that conducts an electric current, ie. a stream of electrons or ions that carry energy in the form of an electric charge (one of their properties).
Example: The ability of a conductor to conduct an electric current is expressed by the quantity electrical conductivity, which is the inverse of the electrical resistance.
sk: vodič
electric charge
noun
Electric charge is a physical quantity that expresses the magnitude of the ability to exert an electric force.
Example: An electrical circuit is a set of elements forming a closed path for an electric charge, a conductive connection of various elements.
sk: elektrický náboj
electric current
noun
Electric current is a physical quantity that expresses the amount of electric charge that passes through the cross section of a conductor per unit time.
Example: The agreed direction of the electric current is opposite.
sk: Elektrický prúd
Electrical engineering
noun
Electrical engineering is a scientific discipline that deals with the study and use of electricity.
Example: Heavy current electrical engineering.
sk: elektrotechnika
electrical resistance
verb
Electrical resistance is a physical quantity that expresses the ability of a material to prevent the passage of electrically charged particles. It is defined as the ratio of the voltage and current flowing through an object as a result of this voltage.
Example: Ohm's law for a part of an electric conductor: the electric current flowing through a conductor is directly proportional to the difference in electrical voltages at the ends of the conductor and indirectly proportional to the electrical resistance of the conductor.
sk: elektrický odpor
electrical voltage
verb
An electric voltage is a physical quantity that expresses the difference in electric potential of two points and represents the energy needed to move an electric charge between those two points in a certain electric field.
Example: The electrical voltage is closely related to the electrical current that arises when an electrical voltage is applied to conductive objects in accordance with Ohm's law.
sk: elektrické napätie
electrolytes
noun
An electrolyte is a compound that is present in solution or melt in the form of ions.
Example: Strong electrolytes - they contain only ions (dissociation took place completely)
sk: elektrolyt
etch
verb
Etching is the process of creating depressions in a material.
Example: Various specialized etchers can be used to etch different surfaces.
sk: leptať
graphile
noun
Graphite is a mineral crystallizing in a hexagonal system, chemically modified by carbon - C.
Example: Carbon in graphite can be of organic or inorganic origin.
sk: grafit
insulator
noun
An insulator or insulation is a substance that insulates, that is, separates one object from another.
An incandescent lamp is a type of electric light source in which light is generated by heating a resistance coil in a vacuum or inert gas using an electric current.
Example: The original Edison bulbs had a carbon fiber, today a tungsten alloy is usually used, which better withstands high temperatures. The tungsten fiber is wound into a spiral (the spiral is approximately 2 cm long, after stretching the fiber is almost a meter).
sk: žiarovka
modeling
noun
Modeling is the process of creating a mathematical three-dimensional object using
specialized software.
Example: Recently, 3D modeling has spread to the general public.
sk: modelovanie
player
noun
A player is a device that stores, organizes, and plays digital music files.
Example: Flash memory based players - these players store digital audio files in internal or external media, e.g. memory card.
sk: prehrávač
power station
noun
A power plant is a technical device and possibly a complex of buildings producing electricity by converting another type of energy.
Example: Nuclear power plants are associated with risks related to the release of radioactivity into the environment and the environmental burden in the form of spent fuel and decommissioned units. Despite these facts, most experts consider nuclear energy to be the cleanest source.
sk: elektráreň
principle
noun
A fundamental truth or proposition that serves as the foundation for a system of belief or behaviour or for a chain of reasoning.
Example: Principle of proportionality and individual approach
sk: zásada
questionnaire
noun
The questionnaire survey is one of the quantitative methods of public opinion research that is widely used in sociology.
Example: Surveys conducted by means of a questionnaire survey can measure sociological phenomena as well as their analysis using mathematical modules and statistical techniques.
