Importance and diversity of power sources - p. 13

Elements and power sources are devices and systems designed to provide electrical energy to various electronic devices and equipment.

Power elements are essential components designed for creating portable or limited-access devices, as well as for use in wireless data transmission. They serve as energy storage sources and include devices such as batteries, accumulators, supercapacitors, and fuel cells.

Batteries are elements that can accumulate and store electrical energy, retaining it in chemical or electrical form. They are widely used in many devices such as mobile phones, laptops, electric vehicles, and other portable electronics.

Batteries are simple and inexpensive power sources used in various devices such as remote controls, wristwatches, or toys. They consist of several galvanic elements connected together and capable of generating electric current.

Supercapacitors are elements used for fast electricity transmission. They are based on the principle of an electric double layer and can store and release a large amount of energy in short periods of time. Supercapacitors are widely used in electronics, transportation vehicles, and other fields where instant supply of high energy is required.

Fuel cells are energy sources that operate based on the reaction between fuel and oxidizer. They provide long-lasting operation of devices without the need for connection to an electrical network. Fuel cells are widely used in the aerospace industry, transportation vehicles, and other fields where a reliable power source is required.
