Quels sont les deux types fondamentaux de transistors bipolaires?
- ADiodes et triodes
- BVaricap et varistor
- CCanal P et canal N
- DNPN et PNP
Correct answer: D — NPN et PNP. Question tirée de la banque officielle d'ISDE.
Why
Bipolar transistors come in two basic arrangements based on how their semiconductor layers are stacked: either a negative layer sandwiched between two positive layers (NPN) or a positive layer between two negative ones (PNP). The full explanation — and one for every question — is in Pro.
