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