Capacitor and Capacitance

Since the late 18th century, capacitors have been used to store electrical energy. Individual capacitors do not hold much energy, providing only enough power for electronic devices during temporary power outages or when they need additional power. Many applications use capacitors as energy sources, and a few of them are as follows: Audio equipment
