Insulator vs. Non-Conductor: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on December 10, 2023
An insulator is a material that resists electric current flow, while a non-conductor is a broader term encompassing materials that impede various forms of energy transfer.

Key Differences

An insulator, in the context of electricity, is a material that significantly resists the flow of electric current. A non-conductor, while often used interchangeably with insulator, can refer to materials that resist not only electrical but also thermal and other forms of energy transfer.

Insulators are specifically designed to prevent the leakage of electric current, providing safety in electrical systems. Non-conductors, on the other hand, may refer to materials that block or reduce the transfer of heat, sound, or other forms of energy, in addition to electricity.

The effectiveness of an insulator is measured by its resistivity to electrical current. For non-conductors, the effectiveness can vary depending on the type of energy transfer it is intended to resist, such as thermal conductivity for heat.
