What is capacitor polarity?
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.
How to identify the poles of a capacitor?

Only by this, the circuit can be completed and the capacitor can operate as expected. Introduction to polar capacitors 101: how to tell the poles apart.
Why do capacitors have negative terminals?
Circuit Board Notations: Sometimes, the negative terminal is marked directly on the circuit board instead of the capacitor. These markings are vital for preventing the reverse installation of capacitors, which can cause device failure or damage. Using a multimeter can help a lot in determining the polarity or terminals of a capacitor.
What is the difference between a positive and a negative capacitor?
Longer Lead: In through-hole electrolytic capacitors, the negative terminal is often connected to the shorter lead, while the positive terminal connects to the longer lead. Datasheet Reference: Consult the capacitor’s datasheet for polarity information, especially when dealing with surface mount electrolytic capacitors.
How do you know if a capacitor is positive or negative?
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.
