Which resistor rating is specified as a given fraction per degree Celsius?
- A Tolerance
- B Power rating
- C Ohmic value
- D Temperature coefficient
Correct answer: D — Temperature coefficient. From the official ISED question bank, verified word for word.
Why
Temperature coefficient describes how much a resistor's resistance changes for every degree Celsius the temperature shifts, expressed as a fraction of the original value. The full explanation — and one for every question — is in Pro.
