Dans un dipôle demi-onde, la distribution ____________ est la plus faible à chaque extrémité.
- Ade la capacité
- Bdu courant
- Cde la tension
- Dde l'inductance
Correct answer: B — du courant. Question tirée de la banque officielle d'ISDE.
Why
In a half-wave dipole, the electrical current is lowest at each end because the wire stops there, forcing the flow of electrons to drop to zero. The full explanation — and one for every question — is in Pro.
