Thus, polarized capacitors can be used in DC circuits only. On the other hand, the non-polarized capacitor is one whose terminal polarity is not fixed, thus this type of capacitor can be used AC circuits as well.

Introduction to Capacitor Technologies
When AC voltage is applied to a capacitor, current starts to flow through its dielectric material and all of its conductive parts such as electrodes and lead wires/terminations. In a practical capacitor, some part of the current passing through the capacitor is dissipated because there is a small amount of resistance to the flow of current.

For large capacitors, the capacitance value and voltage rating are usually printed directly on the case. Some capacitors use "MFD" which stands for "microfarads". While a capacitor color code exists, rather like the resistor color code, it has generally fallen out of favor. For smaller capacitors a numeric code is used that echoes the ...
Electronics/Capacitors
As a capacitor charges, its resistance increases as it gains more and more charge. As the resistance of the capacitor climbs, electricity begins to flow not only to the capacitor, but through the resistor as well: Once the capacitor''s voltage equals that of the battery, meaning it is fully charged, it will not allow any current to pass through ...
Capacitors Insulation Resistance (Capacitor ir)
"Insulation Resistance", then, is a measure of the ability of the dielectric to withstand the passage of electrons through itself and should not be confused with the inherent "series resistance" of the capacitor. For ease of identification, this "insulation resistance" is also referred to as the "parallel" or "shunt" resistance of the capacitor (see Figure 2).
