ElectricianMath.com Electrician Math is a website which presents all electrical calculations
likely to be encountered by an electrician in classes, on the job, and on electrician
examinations. From calculator practice to commercial service calculations, every
electrician can benefit from the content of this electrical math website by
David Ullian Larson.
An electrical apprentice, journeyman electrician, master electrician, and electrical inspector will
find help here to improve calculations technique. Formulas are explained.
Algebra is included. Conversion and derivation of formulas is a large part of
this presentation. Story problems and grid worksheets are backed up with audio
support. Mathematics is used by electricians every day. This website established
a comprehensive coverage of each topic. Several thousand
practice calculations are provided.
The material presented here online is free for all to use. If you need more
support material, printed workbooks and digital download workbooks are also
available.
So where do you begin. You may want to go through a checklist of
calculation types to be sure you understand each type.
Find a Journeyman Electrician Checklist
HERE.
Find a Master Electrician checklist HERE.
Or you may want to start by selecting a calculation type in the
navigation links above that you are not sure about. Read the details about that
calculation type. Get your calculator and code book ready. Do a few of the practice problems. If you
do not understand the
technique, do more until you do understand. There is no time limit to this
activity. You may spend years to perfect all calculation types. If you do
understand the problem type, then move on to the next calculation you want to
investigate.
Along the way you may need to listen to the audio lecture about that
topic. Turn up the volume on your computer and go for it. All this is free for your use.
If you prefer working from a paper workbook, they are available. But you can you can
also buy a digital download for all of these workbooks and
put the workbooks on your computer hard drive to use even if you are not online.
Or print them with your computer. But you do not have to do that. You can just keep coming back to this page until
you understand all the calculation techniques. Compliments of
ElectricianMath.com and
ElectricianEducation.com and
the author, David U.
Larson.
So click on. Have fun. Improve your electrical knowledge. All you need to
spend is the electricity to power your computer and the internet monthly fee.
Set aside the time to improve your electrical knowledge. Place your self on a chair
in front of a computer. Then focus. And have at it. As I often say, Invest In
Yourself.
What's New:
Now the answers to all practice
problems have been added to the website as a free download. Getting all the
files formatted and loaded took me a while. But they are now available online,
and all for
. You can still get a printed version of any workbook you need if you
choose. There are buy now buttons to order with any debit or credit card. But
all worksheets and all answer pages to all 10,000 Journeyman and 10,000 Master
Electrician practice problems are available online to be printed at no charge.
You will need a calculator for many of
these calculations.
A Texas Instruments TI-30Xa calculator for about $12 is the correct
calculator for all calculations on these web pages. No fancy calculator is
needed. The TI-30Xa is perfect for every electrical calculation an electrician
needs to make. Don't get any other version, though. The TI-30Xa has all the
necessary keys for functions which are needed by electricians. If you have some
other calculator, save it for your income taxes. Pry open your wallet, take out
twelve bucks, and buy a TI-30Xa. Instructions are provided based on the TI-30Xa. No, I
do not own stock in the Texas Instruments Corporation. And I have received no
compensation for this promotion. It just happens to be the best calculator for
what an electrician needs a calculator to do.
Find support for the Texas Instruments TI-30Xa calculator HERE.
