Quiz
the measure of electric potential difference between two points in a circuit, expressed in volts
tension, voltage
an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance
résistance, résistor
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
semi-conducteur
a phenomenon where certain materials conduct electricity without resistance when cooled to extremely low temperatures
supraconductivité, superconductivité
to apply an electric charge to a conductor
électrifier, charger électriquement
a conductor through which electricity travels to or from an object, such as batteries
électrode
a form of electricity generated by friction between two materials, resulting in an imbalance of electric charges on their surfaces
électricité statique, électrostatique
(of a battery or device) capable of being supplied with electrical power again
rechargeable, à recharge
a machine that produces electricity by converting mechanical energy into electrical energy
générateur
a positively charged electrode in an electrical device where oxidation occurs, resulting in the release of electrons
anode
a negatively charged electrode within an electrical device, from which electrons flow out into the external circuit
cathode
a device that converts the energy of the sun into electricity
panneau solaire
the amount of solar energy received per unit area on Earth's surface
irradiance solaire, rayonnement solaire
the energy transmitted in the form of particles or waves through the space or a matter
radiation
related to the technology that turns sunlight directly into electricity
photovoltaïque, relatif à la conversion de la lumière en électricité
referring to the combined interaction of electric and magnetic fields, often associated with waves or radiation
électromagnétique
an invisible area around a magnetic object where magnetic forces can attract or repel other objects
champ magnétique, champ d'aimantation
a long rigid bar that is put under a heavy object in order to move it
levier
a point or support on which a lever pivots or rotates in order to lift or move objects
pivot, point d'appui
the rapid back-and-forth movement of an object
vibration, oscillation
a rotational force measured in newton-meters or foot-pounds
couple, moment de force
a measure of a spring's stiffness, indicating how much force is needed to stretch or compress it
constante de ressort, raideur du ressort
a mass used to provide balance to another mass
contrepoids, masse d'équilibrage
having a speed greater than that of sound
supersonique, ultrasonique
(physics) the increase in velocity over time
accélération, augmentation de la vitesse
the constant speed reached by a falling object when the drag force equals the gravitational force pulling it downward, resulting in no further acceleration
vitesse terminale, vitesse limite
the study of the design, development, and operation of aircrafts, focusing on principles of aerodynamics, propulsion, and material science
aéronautique, aviation
a branch of science and engineering that deals with the mechanical properties of liquids, particularly their behavior in confined spaces and under pressure
hydraulique, mécanique des fluides
(physics) the universal force of attraction between any pair of objects with mass
gravité
