Qu'arrive-t-il au courant lorsqu'un circuit RLC série est accordé sur la fréquence de la source?
- AIl atteint le maximum
- BIl est limité par la réactance inductive
- CIl est limité par la réactance capacitive
- DIl atteint le minimum
Correct answer: A — Il atteint le maximum. Question tirée de la banque officielle d'ISDE.
Why
When a series RLC circuit tunes to the source frequency, the opposing effects of the inductor and capacitor cancel each other out, leaving only the resistance to limit the flow. The full explanation — and one for every question — is in Pro.
