Quelle est la fréquence de résonance d'un circuit RLC en série si R = 47 ohms, L = 3 microhenrys et C = 15 picofarads?
- A35,4 MHz
- B35,4 kHz
- C23,7 kHz
- D23,7 MHz
Correct answer: D — 23,7 MHz. Question tirée de la banque officielle d'ISDE.
Why
The resonant frequency is 23.7 MHz because the formula depends only on the inductor and capacitor values, not the resistor. The full explanation — and one for every question — is in Pro.
