Electronic Principles
A farad is defined as the amount of capacitance necessary for:

changing the voltage on the plates at the rate of 1 V per second when 1 A of current is flowing
storing 1 V for 1 second
causing an ac phase shift greater than 90 degree
dissipating 1 W of power
None of these

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

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 has an excessive number of free electrons, while a conductor has a few free electrons or none at all
An insulator allows current to flow much easier than a conductor does
