Electrolytic capacitors are polarized capacitors, meaning they have a positive and negative terminal. They are used in applications that require high capacitance, such as power supplies and audio amplifiers.
Capacitors are common electronic devices that are used to store electric charge for a variety of applications. A capacitor is usually constructed with two conducting plates (called "terminals" or "electrodes") separated by either air or an insulating material. Figure (PageIndex{1}): Two examples of capacitors.
The loads in a power system are usually divided into active and reactive loads. Active load refers to the load that does work to the outside, such as various motors, production equipment, etc. Reactive loads do not do any work, mainly including electrical equipment such as capacitors and reactors.

Filter capacitors, or "caps" for short, are more formally known as electrolytic capacitors. The name is derived from the fact that they are filled with an electrolyte—often in the form of paper soaked in electrolytic gel or liquid—which separates the component''s positive and negative plates.
Before testing the capacitor, ensure it is discharged by shorting its terminals with a resistor (20-100 ohms) until you read the voltage on the capacitor to be zero. Usually, capacitors fail in a short circuit. To test this, you need to measure it outside of the circuit in resistance mode of your multimeter. You''ll measure low resistance at ...
