Which of the following determines if a material is a conductor or an insulator?
1 answer
The conductivity of a material determines if it is a conductor or an insulator. Conductors have high conductivity, allowing electric current to flow easily through them, while insulators have low conductivity, preventing the flow of electric current. Additionally, the presence of free electrons in a material can also determine if it is a conductor or an insulator. Conductors have a high density of free electrons, while insulators have few or no free electrons.
