Quiz
an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance

resistor, motstånd

the complete circle through which an electric current flows, typically consists of the source of electric energy

elektrisk krets, krets

a solid substance that conducts electricity or heat better than insulators, but not as well as most metals

halvledare

a phenomenon where certain materials conduct electricity without resistance when cooled to extremely low temperatures

supraledning

a conductor through which electricity travels to or from an object, such as batteries

elektrod

a positively charged electrode in an electrical device where oxidation occurs, resulting in the release of electrons

anod

a negatively charged electrode within an electrical device, from which electrons flow out into the external circuit

katod

a form of electricity generated by friction between two materials, resulting in an imbalance of electric charges on their surfaces

statisk elektricitet

(of a battery or device) capable of being supplied with electrical power again

uppladdningsbar

a machine that produces electricity by converting mechanical energy into electrical energy

generator, elgenerator

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

solirradians, solstrålning

the energy transmitted in the form of particles or waves through the space or a matter

strålning

related to the technology that turns sunlight directly into electricity

fotovoltaisk

referring to the combined interaction of electric and magnetic fields, often associated with waves or radiation

elektromagnetisk

an invisible area around a magnetic object where magnetic forces can attract or repel other objects

magnetfält, magnetisk område

a point or support on which a lever pivots or rotates in order to lift or move objects

pivot, stödpunkt

a measure of a spring's stiffness, indicating how much force is needed to stretch or compress it

fjäderkonstant, styvhetskoefficient

the study of the design, development, and operation of aircrafts, focusing on principles of aerodynamics, propulsion, and material science

luftfart, flygteknik

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, stabil hastighet

relating to the transmission or control of fluids under pressure within confined systems or machinery

hydraulisk, som rör sig i trycksatta vätskor
