electricity
The video "What is electricity? | STEM kids" explains electricity as the movement or flow of electrons from one atom to another. Atoms, which are the building blocks of everything, have electrons that can move between them. This flow of electrons is called electric current. Some materials, called conductors, allow electrons to move easily, while others, called insulators, do not. To make use of electricity, a complete path or circuit is needed for the electric current to flow, such as using a battery, wires, and a light bulb to create a working electric circuit .
Natural Electricity: Electricity in nature, like lightning, occurs when charges build up in clouds and interact with opposite charges on the ground, creating a high-voltage electric discharge that is extremely hot, hotter than the surface of the sun.
Man-made Electricity: Electricity generated by humans can come from sources such as batteries, power plants, and renewable resources like wind, water, and solar energy. These sources use different methods, such as chemical reactions in batteries or motion in generators, to produce electricity.
Flow of Electrons: The movement of electrons within atoms and through conductors creates electrical energy. This movement can produce static electricity, which is an accumulation of excess charge, or dynamic electricity, which involves a continuous flow of electrons in a circuit.
