Capacitors can be divided into two main groups: 1) electrostatic, non-polarized and 2) polarized capacitors. Polarized capacitors can be then divided into electrolytic and supercapacitors. See the following chart with more details. The latter is by their construction polarity dependent with one plus terminal and one minus. The electrostatics don’t have this polarity dependence in their dielectric which therefore can be subjected also to alternating voltages.
