A capacitor can retain its electric field — hold its charge — because the positive and negative charges on each of the plates attract each other but never reach each other. This will cause equal but opposite charges to build up on each of the plates, until they''re so full they repel any more current from flowing.

Learn MoreCommon polarity markings on capacitors are positive and negative signs that are easy to understand. Plus is the positive terminal, and Minus is the negative terminal. Some capacitors come with color-coded terminals for polarity indication. Such as radial surface-mounted capacitors come with small black-colored parts for the negative pin.
The positive charge on one plate is exactly equal to the negative charge on the other. The polarity of a capacitor refers to the direction of the electric field within the component. This polarity is crucial for the correct operation of the capacitor. Not all capacitors have polarity; it's primarily associated with electrolytic capacitors.
These color codes provide visual cues for polarity identification. Arrow Symbols: In some cases, polarized capacitors may feature arrow symbols pointing towards the negative terminal or away from the positive terminal. These arrow markings indicate the direction of polarity and help users align the capacitor correctly within the circuit.
The polarity of a polymer capacitor is typically indicated by markings on the component itself. Common markings include: Plus (+) and Minus (-) Signs: The positive terminal is usually marked with a “+” sign, and the negative terminal is marked with a “-” sign. Color Coding: Some capacitors use color bands or stripes to indicate polarity.
Damage: If a polarized capacitor is connected with reverse polarity, the dielectric layer can break down, leading to a short circuit or even an explosion. Performance degradation: Even if the capacitor doesn't fail immediately, reverse polarity can cause the capacitor to lose capacitance, increase leakage current, and reduce its overall lifespan.
