Electricity

Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects, such as lightning, static electricity, electromagnetic induction and electric current. In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves.

In electricity, charges produce electromagnetic fields which act on other charges. Electricity occurs due to several types of physics:

Railway electrification system

A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electrification has many advantages but requires significant capital expenditure. Selection of an electrification system is based on economics of energy supply, maintenance, and capital cost compared to the revenue obtained for freight and passenger traffic. Different systems are used for urban and intercity areas; some electric locomotives can switch to different supply voltages to allow flexibility in operation.

Characteristics of railway electrification

Electric railways use electric locomotives to haul passengers or freight in separate cars or electric multiple units, passenger cars with their own motors. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches and transformers.

Electric (Jack Ingram album)

Electric is the fifth studio album by American country music artist Jack Ingram, released in 2003. The only single released was "One Thing", which failed to chart. In 2003 an EP titled Electric: Extra Volts was released, which contained five songs left off this album.

Tellus (comics)

Tellus is a fictional DC Comics superhero and a member of the Legion of Super-Heroes featured in the 30th century. Tellus was co-created by writer Paul Levitz and artist Steve Lightle.

Fictional character biography

Tellus, real name Ganglios, is a native of the methane-atmosphere planet Hykraius. All Hykraians are methane-breathers and cannot survive outside a liquid methane environment without special breathing apparatus (in Tellus' case, a special helmet). Like all members of his race, Tellus was both telepathic and telekinetic, and it was his skill with these powers that helped gain him entry into the Legion Academy and later the Legion itself. He joined the Legion alongside Polar Boy, Magnetic Kid, Sensor Girl and Quislet in Legion of Super-Heroes (third series) #14.

He was the second non-humanoid Legionnaire. (Quislet, who joined at the same time, did not have a body in the normal sense).

Tellus served in the Legion for many years and re-appeared in Legion of Super-Heroes (fourth series), where it was revealed that Tellus had joined Dark Circle, a criminal organization that by then had transformed itself into a quasi-religious organization.

Tellus of Athens

Tellus (Greek: Τέλλος) was an Athenian statesman featured in Herodotus's Histories, in which the wise man Solon describes him as the happiest man ever. To quote Herodotus:

Tellus... had both beautiful and good children, and he saw all his grandchildren from birth and all remaining alive... And the end of his life was most brilliant: for when the Athenians had a war against their neighbours in Eleusis, coming to the rescue and making a rout of the enemy he died most beautifully, and the Athenians had buried him publicly right where he fell, and honoured him greatly.

His "perfect" life helps historians infer Ancient Greek ideals about the most honorable and mentionable way to live.

After describing Tellus as the happiest of all men, Solon states that the second-happiest men ever were the brothers Kleobis and Biton.
