Polarized capacitors have distinct positive and negative terminals. The positive terminal, or anode, must be at a higher voltage than the negative terminal, or cathode, for the capacitor to function correctly. A common type of polarized capacitor is the Electrolytic Capacitor.
The negative terminal (-) of the capacitor is connected to the ground (GND) or negative voltage reference. The schematic provides clear guidance on how to correctly orient the capacitor within the circuit to ensure proper functionality and prevent polarity-related issues.
Capacitor polarity refers to the orientation of positive and negative terminals in a capacitor. In polarized capacitors, the positive terminal (anode) and the negative terminal (cathode) must be connected correctly to ensure proper functioning. Conversely, non-polarized capacitors don’t have this restriction and can be connected in any direction.
When the electrolytic capacitors are polarized, the voltage or potential on the positive terminal is greater that of the negative one, allowing charge to flow freely throughout the capacitor. When the capacitor is polarized, it's generally marked with a minus (-) or plus (+) to indicate the negative and positive ends.
Electrolytic capacitors, a type of polarized capacitor, usually have clear markings indicating the positive (anode) and negative (cathode) terminals. The negative terminal is typically marked with a minus (-) sign, a series of minus signs, or a colored stripe. The positive terminal, on the other hand, is often longer than the negative one.
The existence of polar and non-polar capacitors rises from their differences in the dielectric material between the plates used to store charges. The dielectric material in non-polar capacitors diffuses the positive and negative charges evenly, whilst in polar capacitors, the positive and negative charges are each separated toward a pole.

Is the net charge on a capacitor zero? If yes, then why?
It doesn''t have to always be zero, but in this case, when an uncharged capacitor is connected to a battery in series, the net charge on the capacitor will be zero. The key point here is that batteries provide energy to components, not charge.
