Generally speaking, electrolytic capacitors offer high capacitance per unit volume, are polarized, low cost, high-loss, and exhibit lousy parameter stability. Non-electrolytic device types in contrast tend to be bulky for their ratings, are non-polar, relatively expensive, low-loss, and with a handful of notable exceptions, exhibit fair to ...
Does a capacitor in an AC circuit cause the current to lead or lag the voltage? Current leads the voltage. What is the basic unit of capacitance? Farad. Why should electrolytic capacitors not be used in an AC circuit? They are polarized. An electrolytic capacitor will pass current or one polarity, but will block current of the opposite polarity.
The basic unit of measure for capacitors is the farad (F), which is a large unit often expressed with prefixes like milli-, micro-, nano-, and pico-farads. Capacitance, measured in farads, indicates the capacitor''s ability to store electric charge. The symbol for capacitance is "C."

The capacitance of a capacitor is measured in a unit called the farad. Now, a farad is a pretty big unit, so capacitors used in everyday electronics are usually measured in microfarads (µF), nanofarads (nF), or even picofarads (pF). These smaller units represent a fraction or multiple of a farad, depending on the size of the capacitor.
