For closer tolerances which of the following capacitors is usually preferred ?
Correct answer: B. Mica capacitor
- A. Paper capacitor
- B. Mica capacitor
- C. Ceramic disc capacitor
- D. None of the above
Explanation
Mica capacitors are preferred where close tolerance is needed because mica is mechanically stable and has a highly uniform dielectric. Paper capacitors generally have greater variation with temperature, moisture, and age.
