The Electronics Portal
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow.
Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. (Full article...)

Joseph Henry (December 17, 1797 – May 13, 1878) was a Scottish-American scientist. During his lifetime, he was considered one of the greatest American scientists since Benjamin Franklin. While building electromagnets, he discovered the electromagnetic phenomenon of self-inductance. He also discovered mutual inductance independently of Faraday, though Faraday was the first to publish his results. His work on the electromagnetic relay was the basis of the electrical telegraph, jointly invented by Samuel Morse and Charles Wheatstone. The SI unit of inductance, the henry, is named after him.
In science and technology, a battery is a device that stores chemical energy and makes it available in an electrical form. Batteries consist of electrochemical devices such as two or more galvanic cells, fuel cells or flow cells. The modern development of batteries started with the Voltaic pile, announced by the Italian physicist Alessandro Volta in 1800.
Formally, an electrical "battery" is an interconnected array of similar voltaic cells ("cells"). However, in many contexts (other than the expression dry cell) it is common to call a single cell used on its own a battery. A battery is a device in which chemical energy is directly converted to electrical energy. It consists of one or more voltaic cells, each of which is composed of two half cells connected in series by the conductive electrolyte.

Sirius Satellite Radio is one of two satellite radio (SDARS) services operating in the United States and Canada. (XM Radio is the other provider.) Headquartered in New York City, Sirius provides 69 streams (channels) of music and 65 streams of sports, news and entertainment to listeners. Music streams on Sirius carry a wide variety of music genres, broadcasting 24 hours a day, commercial-free. With most Sirius-enabled radios, the user can see the artist and song information on display while listening to the stream.
