Electronic Principles What is the difference between a conductor and an insulator? 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 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
