Air capacitors are generally available in the range_________?
Correct answer: A. 10 to 400 pF
- A. 10 to 400 pF
- B. 1 to 20 pF
- C. 100 to 900 pF
- D. 20 to 100 pF
Explanation
Variable air capacitors used in tuning circuits are commonly available over approximately 10 to 400 pF. Their low-loss air dielectric makes them suitable for radio-frequency applications.
