Quelles sont les valeurs possibles d'une résistance de 100 ohms dont la tolérance est de 10 %?
- ADe 90 ohms à 100 ohms
- BDe 10 ohms à 100 ohms
- CDe 80 ohms à 120 ohms
- DDe 90 ohms à 110 ohms
Correct answer: D — De 90 ohms à 110 ohms. Question tirée de la banque officielle d'ISDE.
Why
A 10% tolerance means the actual resistance can vary by ten percent above or below the stated 100 ohms. The full explanation — and one for every question — is in Pro.
