nonconductors
Electricity cannot pass
Nonconductors are materials that resist the flow of electricity, heat, or sound.
Rubber, glass, and plastic are common nonconductors of electricity, used to insulate wires and protect against shock.
The term appears mainly in physics and engineering contexts: The handle was made of a nonconductor to prevent burns.
