Essential Electrical Components: Holding the Current
Capacitors are vital parts that store kinetic energy in an electrostatic field. They consist of two layers of metal separated by an dielectric layer. When a voltage is applied across the capacitor, electrons accumulate on one plate, creating a negative charge while the other plate becomes positively charged. This separation of charge forms a reservoir of electrical potential. Capacitors are essential for a variety of applications in electronics, including filtering, smoothing voltage ripples, storing energy for pulsed applications, and timing circuits.
