Electric power where electric current is used to energise equipment

  Electricity is the set of physical phenomena associated with the presence and motion of matter that has a properti of electric charge. Electricity is terkait to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are terkait to electricity, including lightning, static electricity, electric heating, electric discharges and many others. Slot Mesin Online



The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. Bola Online Indonesia


When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain poin in ruang, which is equal to the work done by an eksternal agent in carrying a unit of positive charge from an arbitrarily chosen reference poin to that poin without any acceleration and is typically measured in volts. Situs Slot Terbaik


Electricity is at the heart of many kekinian technologies, being used for:

Elektroniks which deals with electrical sirkuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated sirkuits, and associated passive interconnection technologies.

Electrical phenomena have been studied since antiquity, though progress in theoretical understanding remained slow until the seventeenth and eighteenth centuries. The theory of electromagnetism was developed in the 19th century, and by the end of that century electricity was being put to industrial and residential use by electrical engineers. The rapid expansion in electrical technology at this time transformed industry and society, becoming a driving force for the Second Industrial Revolution. Electricity's extraordinary versatility means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation. Electrical power is now the backbone of kekinian industrial society.[1]
