Here's why:
* Insulators have tightly bound electrons: Unlike conductors, where electrons are free to move, insulators have electrons strongly held within their atomic structure.
* High resistance: This strong binding makes it very difficult for electrons to flow through the material, resulting in high electrical resistance.
Examples of common insulators include:
* Rubber
* Glass
* Plastic
* Wood
* Air
Insulators are crucial for electrical safety. They are used to prevent electrical shocks and short circuits by isolating conductors from each other and from ground.
