Dans un multivibrateur, lorsqu'un transistor conduit, l'autre :
- Aest en polarisation inverse
- Best en polarisation directe
- Cest en mode de coupure
- Dest en mode de saturation
Correct answer: C — est en mode de coupure. Question tirée de la banque officielle d'ISDE.
Why
In a multivibrator circuit designed to switch states, the two transistors work in opposite phases: when one turns fully on to conduct current, the other must turn completely off to stop conducting. The full explanation — and one for every question — is in Pro.
