Dans une diode à semi-conducteur, les électrons circulent:
- Ade l'anode à la cathode
- Bde la source au drain
- Cde la base au collecteur
- Dde la cathode à l'anode
Correct answer: D — de la cathode à l'anode. Question tirée de la banque officielle d'ISDE.
Why
In a semiconductor diode, the actual flow of electrons moves from the cathode to the anode, which is the opposite direction of the conventional current symbol often drawn on circuit diagrams. The full explanation — and one for every question — is in Pro.
