Polarized capacitors have distinct positive and negative terminals. The positive terminal, or anode, must be at a higher voltage than the negative terminal, or cathode, for the capacitor to function correctly. A common type of polarized capacitor is the Electrolytic Capacitor.
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.
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.
If the polarity is reversed, it can lead to the breakdown of the insulating oxide layer, potentially causing the capacitor to fail or even explode. On the other hand, a non-polarized capacitor, also known as a bipolar capacitor, doesn't have a specific positive or negative terminal. This means it can be installed in any direction in a circuit.
Probe Placement: Place the positive (red) probe on the capacitor's positive terminal and the negative (black) probe on the negative terminal. Reading: If the multimeter shows a positive reading or beeps, it indicates that the red probe is on the positive terminal, confirming the capacitor's polarity.
