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

In most cases, electricity is generated by the potential difference (voltage) between two points, such as a battery or an outlet. This potential difference causes electrons to move from the point of lower potential (negative terminal) to the point of higher potential (positive terminal). 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, such as rubber or plastic, can be insulators and prevent electrons from freely flowing.

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