What is Electricity?
Answers
Answer :-
Electricity is the presence and motion of charged particles. How does energy travel through copper wire and through space? What is electric current, electromotive force, and what makes a landing light turn on or a hydraulic pump motor run? Each of these questions requires an understanding of many basic principles. By adding one basic idea on top of other basic ideas, it becomes possible to answer most of the interesting and practical questions about electricity or electronics.
Our understanding of electric current must begin with the nature of matter. All matter is composed of molecules. All molecules are made up of atoms, which are themselves made up of electrons, protons, and neutrons.
Answer:
Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. ... When electrons are "lost" from an atom, the free movement of these electrons constitutes an electric current. Electricity is a basic part of nature and it is one of our most widely used forms of energy.
