Sentences with phrase «electrical insulator»
An electrical insulator is an object or material that does not allow electricity to flow through it easily. It helps to prevent electric currents from passing where they are not supposed to go, ensuring safety and preventing accidents or damage. Full definition

Cholesterol is required everywhere in the brain as an antioxidant, an electrical insulator (in order to prevent ion leakage), as a structural scaffold for the neural network, and a functional component of all membranes.
Some researchers hope to get around such problems by exploiting tiny waves of electrons that exist on the boundary between a metal and an electrical insulator such as glass or silicon.
