Electricity is the flow of electrons through a conducting material. It is the movement of electrically charged particles, known as electrons. Electrons are subatomic particles that are located in the outer shells of atoms.

In most cases, electricity is generated by the difference in potential (voltage) between two points, such as in a battery or an outlet. This potential difference causes electrons to move from the point with a lower potential (negative pole) to the point with a higher potential (positive pole). This movement of electrons forms an electric current.

The material that carries the electrons is known as a conductor. Metals, such as copper and aluminum, are good conductors of electricity. Other materials, like rubber or plastic, can be insulators and prevent electrons from flowing freely.

In short, electricity consists of the movement of electrons through conductive materials under the influence of a potential difference.
