Set of physical phenomena connected with the existence and movement of matter with an electric charge called an electric current. The electromagnetic phenomena, as described by Maxwell’s equations, include both electric current and magnetism. Lightning, electrostatic discharge, electric heating, electric discharges, and many more common occurrences are all linked to electrical current.
The existence of an electric charge, which can be positive or negative, creates an electric field. The passage of electric charges creates a magnetic field, sometimes known as an electric current.
When a charging place in a region has a non-zero electric field, it experiences a force. Coulomb’s law defines the magnitude of this force. The electric field acts on the electric charge if it moved. As a result, we can discuss the electric potential at a certain place in space. It is equal to the work by an external entity in transporting a unit of positive charge from an objectively. It determines the point of comparison to that point without acceleration.
When an electric current is utilized to power equipment, it is referred to as electric power. Electronics is the study of active electronic parts such as vacuum tubes, transistors, diodes, and integrated circuits, as well as the passive connecting techniques that go with them.
Electrical occurrences research since antiquity, although conceptual progress was slow until the 17th and 18th centuries. The theory of electromagnetism was discovered in the nineteenth century. At the end of the century, electrical engineers had put electricity current for commercial and household use.
The rapid growth of electrical technology at the time changed industry and society, pushing the Second Industrial Revolution ahead. Electricity’s incredible adaptability allows it to use in an almost infinite number of applications. It includes transportation, heating, lighting, communication, and calculation. The foundation of modern industrial life is now electrical electricity current.
