Here's a breakdown:
* Electrons: Tiny particles carrying a negative charge. They're the primary carriers of electricity.
* Conductors: Materials with loosely bound electrons that can easily move. These include:
* Metals: Copper, aluminum, gold, silver are excellent conductors.
* Water: Especially when containing impurities like salts.
* Some liquids: Electrolytes like salt water.
* Plasma: Ionized gas with free electrons.
* Insulators: Materials that resist the flow of electrons. These include:
* Rubber: Used to cover wires to prevent shocks.
* Glass: Used in many electrical components.
* Plastic: Common in electrical appliances and devices.
* Air: Acts as an insulator until a high enough voltage causes an arc.
How it works:
When a voltage is applied across a conductor, it creates an electric field that pushes the free electrons through the material. This flow of electrons is what we call electric current.
Key takeaways:
* Electricity is transmitted by the flow of electrons.
* Conductors allow electrons to flow easily.
* Insulators block the flow of electrons.
