Chestionar
the measure of electric potential difference between two points in a circuit, expressed in volts
tensiune, voltaj
an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance
rezistor, rezistență
the complete circle through which an electric current flows, typically consists of the source of electric energy
circuit
a solid substance that conducts electricity or heat better than insulators, but not as well as most metals
semiconductor, semiconductoare
a phenomenon where certain materials conduct electricity without resistance when cooled to extremely low temperatures
supraconductibilitate, superconductibilitate
to apply an electric charge to a conductor
electrifica, încărca electric
a conductor through which electricity travels to or from an object, such as batteries
electrod, conductor electric
a form of electricity generated by friction between two materials, resulting in an imbalance of electric charges on their surfaces
electricitate statică, electrostatică
(of a battery or device) capable of being supplied with electrical power again
reîncărcabil, cu posibilitate de reîncărcare
a machine that produces electricity by converting mechanical energy into electrical energy
generator, alternator
a positively charged electrode in an electrical device where oxidation occurs, resulting in the release of electrons
anod, electrod pozitiv
a negatively charged electrode within an electrical device, from which electrons flow out into the external circuit
catod, electrod negativ
a device that converts the energy of the sun into electricity
celulă solară, fotocelulă
the amount of solar energy received per unit area on Earth's surface
iradiație solară, radiație solară
the energy transmitted in the form of particles or waves through the space or a matter
radiație, iradiere
related to the technology that turns sunlight directly into electricity
fotovoltaic, referitor la tehnologia care transformă lumina solară direct în electricitate
referring to the combined interaction of electric and magnetic fields, often associated with waves or radiation
electromagnetic, referitor la interacțiunea combinată a câmpurilor electrice și magnetice
an invisible area around a magnetic object where magnetic forces can attract or repel other objects
câmp magnetic, zonă magnetică
a long rigid bar that is put under a heavy object in order to move it
pârghie, pied de cabra
a point or support on which a lever pivots or rotates in order to lift or move objects
pivot, punct de sprijin
the rapid back-and-forth movement of an object
vibrație, oscilație
a rotational force measured in newton-meters or foot-pounds
cuplu, moment de forță
a measure of a spring's stiffness, indicating how much force is needed to stretch or compress it
constanta elastică, rigiditatea arcului
a mass used to provide balance to another mass
contragreutate, masă de echilibrare
having a speed greater than that of sound
supersonic, ultrasonic
(physics) the increase in velocity over time
accelerație, creșterea vitezei
the constant speed reached by a falling object when the drag force equals the gravitational force pulling it downward, resulting in no further acceleration
viteză terminală, viteză limită
the study of the design, development, and operation of aircrafts, focusing on principles of aerodynamics, propulsion, and material science
aviație, aeronautică
a branch of science and engineering that deals with the mechanical properties of liquids, particularly their behavior in confined spaces and under pressure
hidraulică, mecanica fluidelor
an area of technology that is concerned with the study or use of robots
robotica, știința roboților
(physics) the universal force of attraction between any pair of objects with mass
