electrical insulator
Stops electron flow
An electrical insulator is a material that resists the flow of electric current—rubber, glass, plastic, ceramic, or dry wood.
Insulators coat wires, separate conductors, and prevent unwanted current paths.
The rubber sheath around a power cord is an insulator; so are the glass or ceramic discs suspending high-voltage lines from utility poles.
