What are the possible values of a 100-ohm resistor with a 10% tolerance?
- A10 ohms to 100 ohms
- B80 ohms to 120 ohms
- C90 ohms to 110 ohms
- D90 ohms to 100 ohms
Correct answer: C — 90 ohms to 110 ohms. From the official ISED question bank, verified word for word.
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.
