Quiz
the measure of electric potential difference between two points in a circuit, expressed in volts
spänning, volt
an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance
motstånd, resistor
the complete circle through which an electric current flows, typically consists of the source of electric energy
krets
a solid substance that conducts electricity or heat better than insulators, but not as well as most metals
halvledare, semiconductor
a phenomenon where certain materials conduct electricity without resistance when cooled to extremely low temperatures
superledning, supraledning
to apply an electric charge to a conductor
elektrifiera, ladda elektriskt
a conductor through which electricity travels to or from an object, such as batteries
elektrod, elektrisk ledare
a form of electricity generated by friction between two materials, resulting in an imbalance of electric charges on their surfaces
statisk elektricitet, elektrostatik
(of a battery or device) capable of being supplied with electrical power again
uppladdningsbar, kan laddas om
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, positiv elektrod
a negatively charged electrode within an electrical device, from which electrons flow out into the external circuit
katod, negativ elektrod
a device that converts the energy of the sun into electricity
solcell, fotovoltaisk cell
the amount of solar energy received per unit area on Earth's surface
solstrålning, solenergi
the energy transmitted in the form of particles or waves through the space or a matter
strålning, radiation
related to the technology that turns sunlight directly into electricity
fotovoltaisk, relaterad till tekniken som omvandlar solljus direkt till el
referring to the combined interaction of electric and magnetic fields, often associated with waves or radiation
elektromagnetisk, som avser den kombinerade interaktionen av elektriska och magnetiska fält
an invisible area around a magnetic object where magnetic forces can attract or repel other objects
magnetfält, magnetiskt område
a long rigid bar that is put under a heavy object in order to move it
hävstång, bräckjärn
a point or support on which a lever pivots or rotates in order to lift or move objects
vridpunkt, stödpunkt
the rapid back-and-forth movement of an object
vibration, oscillation
a rotational force measured in newton-meters or foot-pounds
vridmoment, kraftmoment
a measure of a spring's stiffness, indicating how much force is needed to stretch or compress it
fjäderkonstant, fjäderstyvhet
a mass used to provide balance to another mass
motvikt, balansvikt
having a speed greater than that of sound
supersonisk, ultraljuds-
(physics) the increase in velocity over time
acceleration, hastighetsökning
the constant speed reached by a falling object when the drag force equals the gravitational force pulling it downward, resulting in no further acceleration
terminalhastighet, gränshastighet
the study of the design, development, and operation of aircrafts, focusing on principles of aerodynamics, propulsion, and material science
flyg, flygteknik
a branch of science and engineering that deals with the mechanical properties of liquids, particularly their behavior in confined spaces and under pressure
hydraulik, strömningsmekanik
an area of technology that is concerned with the study or use of robots
