Electronic Principles
What is the difference between a conductor and an insulator?

An insulator allows current to flow much easier than a conductor does
A conductor allows current to flow much easier than an insulator does
None of these
The difference between conductors and insulators depends on how they are used
An insulator has an excessive number of free electrons, while a conductor has a few free electrons or none at all
