The capacitor preferred for high frequency circuits is_____________?
Correct answer: B. mica capacitor
- A. air capacitor
- B. mica capacitor
- C. electrolytic capacitor
- D. none of the above
Explanation
Mica capacitors are valued in high-frequency circuits because mica has low dielectric loss, good stability, and small leakage. Electrolytic capacitors are generally unsuitable for high-frequency operation because of their higher losses and parasitic effects.
