Electricity

Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to electromagnetism.

Electricity is at the heart of Type 0 technologies, being used for:


 * Electric power where electric current is used to energize equipment.
 * Electronics which deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits.

The rapid expansion in electrical technology becomes a driving force for the Second Industrial Revolution.
