Des tolérances de résistance suivantes, laquelle est de plus haute précision?
- A20 %
- B0,1 %
- C5 %
- D10 %
Correct answer: B — 0,1 %. Question tirée de la banque officielle d'ISDE.
Why
A tolerance of 0.1% means the actual resistance value will be extremely close to the printed number, allowing for only a tiny fraction of error. The full explanation — and one for every question — is in Pro.
