The Nature of Electricity?
Definition of electricity
The flow of electrons through a conductor due to an electric potential difference.
The fundamental properties of electricity
When a negatively charged object is connected to a positively charged object through a conductor, excess electrons flow from the negative body to the positive body to balance the electron shortage.
Atomic structure
An atom consists of a nucleus with protons and neutrons, surrounded by electrons.
Free electron
Loose bonds combine electrons that can move from one atom to another called free electrons.
Conductor
Materials with many free electrons, such as copper and aluminum, are good conductors of electricity
Insulator
Materials with few free electrons, such as glass and mica, are poor conductors of electricity
