Does a capacitor have positive and negative terminals?
Electrolytic capacitors have a positive and negative side. To tell which side is which, look for a large stripe or a minus sign (or both) on one side of the capacitor. The lead closest to that stripe or minus sign is the negative lead, and the other lead (which is unlabeled) is the positive lead.
How to distinguish the polarity of capacitors | Leadsintec
The basic principle is that when the anode of an electrolytic capacitor is connected to the positive terminal of a power source (with the black lead of the multimeter for resistance measurement) and the cathode to the negative terminal (with the red lead), the current passing through the capacitor will be small (i.e., the leakage resistance will be high).

Conversely, if the AC source is at -0.5 V, while the capacitor is at 0.7 V, current will flow in the positive direction while the voltage source is negative. So there could be situation where the capacitor overpowers the voltage source and current flows in a direction opposite to the voltage source''s direction.

What does a positive & negative capacitor mean?
We’ll see what that means shortly. One side of the capacitor is connected to the positive side of the circuit and the other side is connected to the negative. On the side of the capacitor you can see a stripe and symbol to indicate which side in the negative, additionally the negative leg will be shorter.
Do capacitors have a positive and negative terminal?
Most capacitors have a positive and negative terminal. We need to make sure that the capacitor is connected correctly into the circuit. One of the most common applications of capacitors in large buildings is for power factor correction.
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.
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.
