Quel est le facteur de qualité (Q) d'un circuit RLC parallèle quand la résonance = 3,625 MHz, L = 43 microhenrys et R = 1,8 kilohm?
- A1,84
- B0,543
- C54,3
- D23
Correct answer: A — 1,84. Question tirée de la banque officielle d'ISDE.
Why
The value 1.84 is correct because the quality factor, or Q, for a parallel circuit measures how sharply it resonates by comparing resistance to reactance. The full explanation — and one for every question — is in Pro.
