Lesson 35: General Class Exam Course G0B

Here is lesson 35, the last lesson in the General Class Exam Course!  This final lesson focuses on electrical safety rules.  There are a few numbers you will need to memorize:

-The minimum wire size for a 20 ampere current is AWG #12.
-The fuse you would want to install along AWG #14 wire is a 15 ampere fuse.
-60 Hz alternating current is more dangerous to humans than direct current or RF energy.
-The maximum amount of current that can run through a human body without causing damage is 50 microamperes.

That's it!  I hope these videos helped you in your studies for the General Class exam!  Until the next series of lessons...

  1. So bummed. I really hoped the last part of the final video would have firecrackers, a radio beaming from a station, or confetti.

    So glad to be through the lessons!

    Thanks for all the hard work.

  2. Thanks!

    Even though the question pool may be dated I just sat for the General exam and with your prep was well prepared and passed! Thanks so much for the time and effort it took to put this series together.

    I'm really glad I found this material and used it to prepare.
