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 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
An insulator allows current to flow much easier than a conductor does

What is the primary difference between primary and secondary cell batteries?

Secondary-cell batteries can be recharged and used many times, whereas primary-cell batteries cannot be properly recharged
Primary-cell batteries must be recharged at a much slower rate that secondary-cell batteries
Primary-cell batteries use chemical cells, whereas secondary-cell batteries use an alternative energy source, such as thermal or magnetic energy, to supplement their outputs
Primary-cell batteries can be recharged and used many times, whereas secondary-cell batteries cannot be properly recharged
None of these
