How it works
A capacitor is an electronic component that stores and releases electrical energy. It consists of two conductive plates separated by an insulating material called a dielectric.
Charging a Capacitor
When a voltage is applied across the capacitor, electrons accumulate on one plate, creating a negative charge, while the other plate loses electrons, becoming positively charged. This separation of charge creates an electric field in the dielectric, storing energy.
Storing Energy
The capacitor holds this charge as long as the voltage is applied. The amount of charge it can store depends on its capacitance (measured in Farads, F) and the applied voltage.
Discharging a Capacitor
When the voltage source is removed or a conductive path is provided, the stored charge flows from one plate to the other, releasing the stored energy. This process is used in many applications, like smoothing power supply outputs, timing circuits, and energy storage.
