Které z následujících tvrzení o tranzistoru je správné?
Správná odpověď je: A, B, C, D
Tranzistor je polovodičová součástka skládající se ze dvou PN přechodů. Existují 2 typy tranzistorů nazvané dle vzájemné polohy polovodičů typu P a typu N v tranzistoru, typ PNP a NPN. Střední část tranzistoru je tvořena tenkou vrstvou nazývanou báze (B), která je PN přechody oddělena od širších okrajových částí nazvaných kolektor (C) a emitor (E). Tranzistor se nejčastěji využívá jako zesilovač elektrického proudu nebo napětí. Od tranzistoru byly odvozeny další elektrotechnické součástky, mezi něž patří např. fototranzistor, což je tranzistor, v němž je regulace protékajícího proudu závislá na dopadajícím světle v důsledku fotoelektrického jevu.
