Out of the list of resistor tolerances below, which has the highest precision?
- A 0.1%
- B 5%
- C 10%
- D 20%
Correct answer: A — 0.1%. From the official ISED question bank, verified word for word.
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.
