Caution: Do not proceed with any other mathematics aspects of this online electrician exam prep material until you fully understand the solutions to each of these problem types. Seek help from anyone that can instruct you in these calculations. Most calculations will seem basic. But if there are any that are not known to you, then you must seek complete understanding before proceeding.

If you have no one available to help you master these calculations, you may access audio support from me by clicking on the problem number on the answer sheet. I will offer a brief audio explanation for each problem. You may replay an explanation as many times as you need to understand the technique of solution. Question 9 takes a while to load on a dial-up connection. Have patience.

Make sure your speakers are on and the volume is turned up.
