Capacitor
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.
How do supercapacitors work?
Photo: Typical electrolytic capacitors in an electronic circuit. Each one stores a fraction as much energy as a battery, but can be charged and discharged instantly, almost any number of times. Unlike in a battery, the positive and negative charges in a capacitor are produced entirely by static electricity; no chemical reactions are involved.
Transformer
Transformer is the simplest device that is used to transfer electrical energy from one alternating-current circuit to another circuit or multiple circuits, through the process of electromagnetic induction.A transformer works on the principle of electromagnetic induction to step up or step down voltage. Transformer either increases AC voltage (Step-up transformer) …
Static Electricity: Definition, Examples & Use | Vaia
Dangers of Static Electricity: Aircrafts. Electricity on the outside of aeroplanes is formed in 3 different ways. Electricity generated by a lightning strike during flight, static electricity generated by friction as the aircraft passes through snow, ice, hail, or dust clouds, and static electricity generated by electronic devices.

7.7: Applications of Electrostatics
The first was built by Robert Van de Graaff in 1931 (based on original suggestions by Lord Kelvin) for use in nuclear physics research. Figure (PageIndex{1}) shows a schematic of a large research version. Van de Graaffs use both smooth and pointed surfaces, and conductors and insulators to generate large static charges and, hence, large ...

Those given by electricians were among the most popular. (The word electrician originally referred to a person knowledgeable in the nature of static electricity.) Electricity was a hot topic in the 18th century and much exploration was being done with electrostatic machines that generated charge by friction.
Energy Scavengers: Static Electricity Could Power the World
A TENG relies on the same principle as static electricity: When two different materials come into contact, electric charges can accumulate on one, leaving the other with the opposite charge. In the case of that plastic sphere in Wang''s hand, charges accumulate when the interior and exterior balls touch and separate, over and over.
