Quiz
the electronic potential and force whose measurement unit is volts
spänning
an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance
resistor
the complete circle through which an electric current flows, typically consists of the source of electric energy
elektrisk 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
