Because current cannot pass through them. They stop one part of a circuit from interfering with another.

Insulators
Not really, insulators simply cannot support the passage of an electric current.
Electrical current cannot pass through materials that are insulators, such as rubber, glass, plastic, and ceramic. These materials have tightly bound electrons that do not move easily, preventing the flow of electricity.
Electrical current cannot pass through materials that are insulators, such as rubber, glass, plastic, and wood. These materials do not allow the flow of electrons due to their high resistance to electric current.
Insulators have high resistance to the flow of electric current due to their tightly bound electrons which do not allow the movement of free electrons. This prevents the flow of electricity through the material, causing it to effectively block the current.
Materials that electrical current cannot pass through are called insulators. Insulators are often used to protect against electrical shocks and to prevent current leakage in electronic devices. Examples of common insulating materials include rubber, glass, and plastic.
No, electricity cannot pass through insulators. Insulators are materials that do not allow the flow of electric current due to their high resistance to electrical conduction. This property makes insulators important for protecting against electrical shock and for insulating wires and components in electrical systems.
No, electricity cannot travel through wax as it is an insulator. Insulators such as wax do not conduct electricity and therefore do not allow electric current to pass through them.
Electricity cannot pass through insulators because they have high electrical resistance, which hinders the flow of electric current. Insulators have tightly bound electrons that do not move freely, preventing the conduction of electricity. This property makes insulators useful for protecting against electric shocks and for insulating electrical wires.

An insulator. Insulators are materials that do not conduct electricity well and have high electrical resistance, preventing the flow of current through them. Examples include rubber, glass, and plastic.
