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.
To mitigate these issues, capacitors are placed in parallel with the power supply. When the voltage rises above the desired level, the capacitor charges up, storing the excess energy. When the voltage drops below the desired level, the capacitor discharges, releasing the stored energy to maintain a stable voltage.
The higher the capacitance, the more energy the capacitor can store for a given voltage. This energy storage capability is essential in various applications, such as power supplies, where capacitors help smooth out voltage fluctuations and provide a stable power source.
When a voltage is applied across the plates, an electric field is created, causing electrons to accumulate on one plate while the other plate develops a positive charge. This process allows the capacitor to store electrical energy in the form of an electrostatic field.
A Leyden Jar was an early example of a capacitor. Capacitors are another element used to control the flow of charge in a circuit. The name derives from their capacity to store charge, rather like a small battery. Capacitors consist of two conducting surfaces separated by an insulator; a wire lead is connected to each surface.
