Restitorium[1] est elementum electronicum simplicissimum, quod liberam electronum fluxionem impedit.[2] Restitoria e materia insulatoria faciuntur. Magnitudo vehementiae qua restitorium fluxionem electricam impedit dicitur resistentia, cuius mensuralis unitas est "Ohmium," (symbolum Ω).
Dissipatio calorifica
[recensere | fontem recensere]Omnia restitoria potestatem electricam dissipant, itaque calorem generant.[2]. Calor saepe non quaeritur, sed certae machinae, exempli gratia furnus electricus, restitoriis utuntur ut calefaciant aut accendant.
Potestas electrica P quam resistorium resistentiae R dissipat est
ubi P est Wattiis vel Juliis in temporis secundo.
