Jul 23, 2025 · An insulator is a material that does not allow electricity, heat, or sound to flow through it. In other words, insulators are substances that do not allow electrons, sound waves or heat to pass …

An insulator is defined by its primary function of blocking the flow of electric current. A dielectric is an insulator that, when placed in an external electric field, can be polarised.

Jan 16, 2025 · An insulator is a material designed to block the flow of electricity, heat, or sound. Its main role is to provide separation and support for electrical conductors, ensuring that current doesn’t pass …

Jun 11, 2023 · An insulator is a material that doesn’t conduct electric current easily, offering high electrical resistance, low thermal conductivity, and dielectric strength.

The meaning of INSULATOR is one that insulates. How to use insulator in a sentence.

Insulators are available in various materials, including glass, plastic, rubber, and air. Light bulbs, power lines, and electrical cables are all examples of insulators.

From overhead power lines to household appliances, insulators ensure electricity flows only where it’s intended. In this article, we’ll explain insulator types, functions, and why choosing the right one is vital …
