Energy Storage | Applications | Capacitor Guide
Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
Capacitor Energy Calculator
A capacitor is a device that stores electrical charge. The simplest capacitor is the parallel plates capacitor, which holds two opposite charges that create a uniform electric field between the plates.. Therefore, the energy in a capacitor comes from the potential difference between the charges on its plates.

How do capacitors work?
1800: Italian physicist (and battery inventor) Alessandro Volta (1745–1827) coins the (confusing) word "condenser" for a charge-storing device. Capacitors are still sometimes known as condensors to this day, though the term has largely fallen out of favor now. Quite a few of them use capacitors for timing or plain energy storage. Treats
