Course EE-1:Important Electrical Formulas & Unit Conversion Tables.

1- Important Electrical Formulas:

An important foundation for all electrical design & installations is a thorough knowledge of the laws that govern the operation of electricity. The general laws are few and simple, and you can free download a lot of documents containing these formulas and laws as follows:

Basic and important electrical formulas #1

Basic and important electrical formulas #2
Basic and important electrical formulas #3
Basic and important electrical formulas #4
Basic and important electrical formulas #5
Basic and important electrical formulas #6
Basic and important electrical formulas #7
Basic and important electrical formulas #8




I put (8) nos. different documents containing Basic and important electrical formulas to permit each one of you to choose, print and file the most likely one to you for your use through this course.

You can find detailed information about basic electrical formulas in topic: General Basics of Electricity.



2- Unit Conversion Tables:

With these above formulas sheets, we will need also to put the important unit conversions documents , the Conversion of units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors

The process of conversion depends on the specific situation and the intended purpose. This may be governed by regulation, contract, Technical specifications or other published standards, and you can free download a lot of documents containing these unit conversions table as follows:

Unit conversions table #1 

Unit conversions table #2 

Unit conversions table #3 

Unit conversions table #4 

Unit conversions table #5 

Unit conversions table #6 

Please Free download the (6) nos. conversion tables, print and file  the most likely one to you for your use through this course.


There are many programs are designed to do the units conversion automatically, they are very easy and simple use, and you can free download a lot of these programs used for unit conversions as follows:
