Which of the following capacitors preferred for high frequency circuits ?
Correct answer: C. Mica capacitor
- A. Air capacitor
- B. Electrolytic capacitor
- C. Mica capacitor
- D. none of the above
Explanation
Mica capacitors have low dielectric losses, good stability and a high self-resonant frequency, making them suitable for high-frequency circuits. Electrolytic capacitors have greater losses and are mainly used for low-frequency filtering and smoothing.
