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

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