L'ondemètre dynamique ("dip meter") s'applique directement aux :
- Acircuits syntonisés en parallèle
- Bcircuits d'amplificateurs sous tension
- Ccircuits logiques numériques
- Dcircuits syntonisés en série
Correct answer: A — circuits syntonisés en parallèle. Question tirée de la banque officielle d'ISDE.
Why
A dip meter works by placing a small coil near a circuit to detect when energy is absorbed, which happens most clearly when the circuit is a parallel tuned circuit, also known as a tank circuit. The full explanation — and one for every question — is in Pro.
