Glass bangle, thick thread and rubber pipe metal all are non-metal while steel spoon is a metal thing. And we know that only metals conduct electricity that’s why they are conductors and non-metals do not conduct electricity that is why they are insulators. Glass, thread and rubber are insulators and steel spoon is a conductor. Hence, insulators does not allow the current to flow.
|Materials that permit electricity or heat to pass through it||Materials that do not permit heat and electricity to pass through it|
|A few examples of a conductor are silver, aluminum, and iron||A few examples of an insulator are paper, wood, and rubber|
|Electrons move freely within the conductor||Electrons do not move freely within the insulator|
|The electric field exists on the surface but remains zero on the inside||The electric field doesn’t exist|
