This index refers to workbook pages for the Journeyman Electrician License Exam Prep Course
 
Apprentice workbook links are included in the assignment pages.
 
Hyperlinks are included where available to minimize the amount of typing needed to access these audio files.

If you do not have RealAudio on your computer, you will need to get the program loaded on your computer.

Lectures Online

There are audio lectures for many of the Journeyman Calculations assignment pages. The computer you use for this instructional program aspect must have the Real Audio program so you can hear the lectures. You can determine if you have this by doing the following:
Make sure you have speakers connected to the computer; Or headphones if you are in the library. Make sure the volume is turned up. Now for the test. Click HERE.
If you hear the lecture, great. If you do not hear an audio message after a minute or so, download the $9.95  Real Audio Program or buy a cd at any computer store.. 
Click the icon here to be connected to the Real Player page and determine how you want to load the program on your computer.

Here is the link for the page where you can get the  download. Click HERE.
If you do not want to bother getting this sort of message, do not download the program. Instead, go to the nearest office supply store and buy a Real Player disc for about $9.95. Load it and you are ready.
Just follow the directions when you are prompted. Don't be afraid. It is painless and is essential. Let someone help you if it is difficult. Most 12 year olds can do this. I had help the first time. Once it is installed, you will never need to do it again until you get a different computer. 
Notice that Real Audio window has a pause button you can click. Also there is a sliding bar that can be dragged back if you want to repeat something. Play around with it. Here is a musical link just for fun. Click it:

Play with the pause button and sliding scale for a repeat or fast forward. Neat, eh?

 

Journeyman Electrician Calculations Workbook 

Workbook pages which have audio lectures are underlined. Just click the page number which corresponds to the page number to hear the lecture. Some pages may not have a hyperlink. I will add additional audio files as time permits. I hope what you hear will help you master these calculations techniques.
