* Glass is an insulator: Glass is a very poor conductor of electricity. This means it strongly resists the flow of electric current. Electrons are tightly bound within the structure of glass, making it difficult for them to move freely.
* Conductors allow current flow: For an electric circuit to work, you need materials that allow electrons to flow easily. Metals like copper and aluminum are excellent conductors because their electrons are loosely bound and can move freely.
In summary: While glass can be used in some electrical components (like the insulating casing around wires), it cannot be used as the main conductor in a circuit because it does not allow the flow of electricity.
