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 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 ANSWER DOWNLOAD EXAMIANS APP
