From energy storage and voltage regulation to signal filtering, circuit protection, and timing and oscillation, capacitors play a vital role in ensuring the proper operation and performance of electronic systems. Understanding the functions of capacitors is essential for anyone involved in electronic design or troubleshooting.
When a sudden voltage surge occurs, a capacitor can absorb the excess energy, preventing it from reaching sensitive components and causing harm. This protective function is often utilized in power supply circuits, where capacitors are placed across the power rails to suppress voltage spikes and transients.
As a beginner, it is important to understand the functions of capacitors in a circuit. A capacitor is a passive electronic component that is capable of storing and releasing energy. Its unique characteristic lies in its ability to block direct current while allowing alternating current to pass through.
When voltage is applied, an electric charge accumulates on the plates, allowing for temporary energy storage. Moreover, capacitors can smooth out power fluctuations, helping stabilize circuits by temporarily holding and releasing charge. Plates: Conductive materials that store opposite charges for energy storage.
Filter capacitors are used in power circuits to rectify AC into pulsating DC and smooth it through charging and discharging. They are usually large electrolytic capacitors. Decoupling capacitors reduce interference in the output signal by providing a local DC power supply to the active device.
Capacitors are also used to maintain the voltage at a certain level. They are useful in reducing the voltage pulsation. When a high voltage is applied to the parallel circuit, the capacitor is charged, and conversely, it is discharged with the application of a low voltage.

Electronics/Capacitors
Charging creates a charge imbalance between the two plates and creates a reverse voltage that stops the capacitor from charging. As a result, when capacitors are first connected to voltage, charge flows only to stop as the capacitor becomes charged. When a capacitor is charged, current stops flowing and it becomes an open circuit.
