Quelle est la fréquence de résonance d'un circuit RLC parallèle si R = 4,7 kilohms, L = 200 microhenrys et C = 10 picofarads?
- A7,96 kHz
- B3,56 MHz
- C3,56 kHz
- D7,96 MHz
Correct answer: B — 3,56 MHz. Question tirée de la banque officielle d'ISDE.
Why
The resonant frequency is 3.56 MHz because it depends only on the inductor and capacitor values, not the resistor. The full explanation — and one for every question — is in Pro.
