Dans un dipôle demi-onde, la distribution __________ est la plus élevée à chaque extrémité.
- Adu courant
- Bde l'inductance
- Cde la capacité
- Dde la tension
Correct answer: D — de la tension. Question tirée de la banque officielle d'ISDE.
Why
In a half-wave dipole, the electrical pressure, known as voltage, builds up to its strongest point at the very tips of the antenna wires because the current cannot flow past these open ends. The full explanation — and one for every question — is in Pro.
