Capacitors
A capacitor, however, can have either side be positive or negative; The polarity is determined by how you charge the capacitor. If you hook up the capacitor to a power source, the side connected to the positive side of the source will become positively charged, and the side connected to the negative side of the source will become negatively charged.
Where to connect the positive and negative poles of the capacitor

6 Frequently Asked Questions about “Connect the positive and negative poles of the capacitor to the power supply”
Do capacitors have a positive and negative polarity?
Capacitors, especially electrolytic ones, have a positive and negative terminal. It's crucial to connect them correctly to avoid damage. Incorrect polarity can lead to the capacitor overheating, leaking, or even exploding. The longer lead is usually positive. Always refer to the datasheet or circuit diagram for specific polarity markings.
What is capacitor polarity?
Capacitor polarity determines how you connect your capacitor to a circuit. For the case of polarized capacitors, you'll have to connect the positive and negative poles to the power source's positive and negative terminals, respectively.
How do you connect a polarized capacitor?
Therefore, you must connect your polarized capacitor in the direction of your circuit polarity. The positive (+) and negative (-) capacitor polarity symbols on your component are what we refer to as capacitor polarity markings. Generally, the positive terminal indicates the anode, while the negative one indicates the cathode.
What are the polarity markings on a capacitor?
Common 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.
How do polarized capacitors work?
They consist of two conductive plates separated by a dielectric material. In polarized capacitors, such as electrolytic capacitors, it's crucial to connect them in a certain way, ensuring that the positive terminal is connected to the positive side of the circuit and the negative terminal to the negative side.
Do non polarized capacitors have a positive or negative terminal?
Non-polarized capacitors do not have a positive or negative terminal and can be connected to a circuit in any polarity. For optimal performance, you must orient polarized capacitors in the correct direction since they have positive and negative terminals, making them essential components.
