A 10 V power supply would use ____________ as filter capacitor?
Correct answer: C. electrolytic capacitor
- A. paper capacitor
- B. mica capacitor
- C. electrolytic capacitor
- D. air capacitor
Explanation
A 10 V power supply commonly uses an electrolytic capacitor because it provides large capacitance for smoothing rectified voltage and is available with suitable voltage ratings. Paper, mica and air capacitors are generally used for smaller capacitance or specialised applications.
