An electrolytic capacitor is generally made to provide__________?
Correct answer: D. large value of capacitance
- A. low capacitance
- B. fixed capacitance
- C. variable capacitance
- D. large value of capacitance
Explanation
Electrolytic capacitors achieve high capacitance using a very thin oxide dielectric and a large effective electrode area. They are therefore commonly used where large capacitance values are required, especially in DC smoothing.
