Conductors vs. Insulators: Know the Difference
By Shumaila Saeed || Published on January 4, 2024
Conductors allow easy flow of electricity and heat due to free electrons, while insulators resist this flow, having tightly bound electrons.
Key Differences
Conductors are materials that allow electricity and heat to pass through them easily, due to their free-moving electrons. Insulators, in contrast, have tightly bound electrons, preventing the easy flow of electricity and heat.

Conductors, like copper and aluminum, are often used in electrical wiring due to their high electrical conductivity. Insulators such as rubber and glass are used to coat or surround conductors to prevent electrical accidents.

In conductors, the atoms have loosely held electrons that can move freely, facilitating the flow of current. Insulators have electrons that are tightly bound to their atoms, making them poor conductors of electricity.

Conductors are typically metals or metal alloys, and their ability to transfer heat makes them useful in cooking utensils. Insulators, being poor conductors of heat, are used in thermal insulation materials.

Conductors can become charged by conduction, gaining or losing electrons easily. Insulators, however, do not easily transfer charge and are used in static charge applications.
