Which of the following is characteristic of an electrolytic capacitor?
Tight tolerance
Much less leakage than any other type
High capacitance for a given volume✓الإجابة الصحيحة
Inexpensive RF capacitor
الشرح
An electrolytic capacitor's dielectric is an extremely thin oxide layer formed chemically on the plate, and capacitance rises as the dielectric gets thinner, so a large value fits in a small package. That construction also means loose tolerance and comparatively high leakage, so those choices are wrong.
