Quel est le facteur de qualité (Q) d'un circuit RLC parallèle quand la résonance = 7,125 MHz, L = 12,6 microhenrys et R = 22 kilohms?
- A22,1
- B0,0256
- C25,6
- D39
Correct answer: D — 39. Question tirée de la banque officielle d'ISDE.
Why
The value 39 is right because the quality factor, or Q, measures how sharply a circuit resonates by comparing the energy stored to the energy lost. The full explanation — and one for every question — is in Pro.
