Capacitor polarity: everything you need to know
Most capacitors have a mark or indication on one of their terminals to indicate their polarity. This mark can be a line, a "+" symbol or a letter "P", among others. In case the terminal does not have a marking, it is important to consult the capacitor specification sheet or circuit diagram to determine its polarity.
How do capacitors work?
Artwork: A dielectric increases the capacitance of a capacitor by reducing the electric field between its plates, so reducing the potential (voltage) of each plate. That means you can store more charge on the plates at the same voltage. The electric field in this capacitor runs from the positive plate on the left to the negative plate on the right.
Capacitor Discharge
In AC circuits, a capacitor''s current and voltage have a 90-degree phase difference In this figure, V(t) is the voltage depending on time, i(t) is the current depending on time, Vm is the peak value of the voltage of the capacitor, Im is the peak value of the alternative current going through the capacitor, and θ is the phase difference between the voltage and the current of the capacitor.
The Fundamentals of Capacitors in AC Circuits
The phasor diagram shown in Figure 1 shows a current phasor leading the voltage by 90°. Capacitive Reactance. When an ac voltage is applied to a capacitor, it is continually being charged and discharged, and current flows in and out of the capacitor at a regular rate, dependent on the supply frequency.

18.5 Capacitors and Dielectrics
The top capacitor has no dielectric between its plates. The bottom capacitor has a dielectric between its plates. Because some electric-field lines terminate and start on polarization charges in the dielectric, the electric field is less strong in the capacitor. Thus, for the same charge, a capacitor stores less energy when it contains a ...

Capacitor Tutorial Summary
When a capacitor is connected across a source it observed electrical energy and store it in the form of electrostatic energy. This is because of the accumulation of positive ions on the plates connected to the positive side of the source and negative ions on the side of the capacitor connected to negative side of the source.

Polarized capacitors are only rated for voltage potentials in one direction. They like to collect charge in one polarity on their plates. A non-polarized capacitor such as generic ceramic types are capable of collecting charge in both positive and negative polarity (you can use them in circuits that have voltages that swing both above and below your zero/GND reference).
