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.
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.
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.
1. 2. Non-polar Capacitors Polar capacitors or polarized capacitors are such type of a capacitor whose terminals (electrodes) have polarity; positive and negative. The positive terminal should be connected to positive of supply and negative to negative. Reversing the polarity will destroy the capacitor.
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.
Polar capacitors or polarized capacitors are such type of a capacitor whose terminals (electrodes) have polarity; positive and negative. The positive terminal should be connected to positive of supply and negative to negative. Reversing the polarity will destroy the capacitor. These type of capacitors are only used in DC applications.

Live ChatIdentifying the positive and negative terminals of capacitors is essential for proper circuit connectivity and operation. Follow these steps to identify capacitor terminals:
Live ChatThe shorter lead is the negative lead and the longer lead is the positive lead. If you clip the leads, you can still look for the stripe or minus sign. The value of most electrolytic capacitors is marked on the case. Other types of capacitors are so small that there''s not enough room for the value, so manufacturers use a code.

Live ChatThe 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).

Live ChatConversely, 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.
