Thermistors are made of__________________?
Correct answer: D. Metal oxides
- A. Ultra pure metals
- B. Nickel-chromium alloys
- C. Iron-copper alloys
- D. Metal oxides
Explanation
Thermistors are temperature-sensitive semiconductor resistors commonly manufactured from sintered metal oxides such as oxides of manganese, nickel, cobalt, or copper. Pure metals are used in resistance thermometers rather than thermistors.
