In this LearnElectrics video we will explore Ohm’s Law and Power Law and show you the Power Matrix.
These formulas are so very useful, they can quickly and accurately help you to choose the right size breaker for example, or work out diversity and lots more, if you know how to manipulate the numbers.
Ohm’s Law is probably the most taught formula in the electrical trade. Together with Power Law it is essential that we know how to use it and in this video, we show you worked examples of all the formulas, and examples for you to try yourself.
There are always lots of questions about ohm’s law and power calculations…
How do we use ohm’s law?
How does the power triangle work?
Can we combine the triangles together?
If I know just two values, can I work out the others?
And many more interesting questions.
To get a printable PDF of the Power Matrix ...
1/ Go to LearnElectrics.com on your web browser
2/ Enter P192 into the search box and a page will open up with a link to the PDF
To view all our videos type in LearnElectrics all one word into the RU-vid search bar.

I have use these formulas many times in my 40 year career as an electrician. These are must know calculations.

@learnelectrics4402 Год назад

Thanks for the supporting comment Lyle. Much appreciated. Dave.

@danielteyehuago1633 Год назад

Wow! This is very informative, thanks for sharing it with us. It worth it and the best tutorial on the topic for me.

Great little matrix, thanks for posting! 👍👍

@learnelectrics4402 Год назад

Glad you like it, thanks for supporting the channel.

@danielteyehuago1633 Год назад

I was expecting to see the application of these formulae, but I didn't see it... Thanks

@learnelectrics4402 Год назад

This video is just about using the matrix, Thanks for watching.

@martinburgess2322 Год назад

Thanks Dave.👍always good to brush up on some maths😀spot on as always.

@learnelectrics4402 Год назад

Problem with the direct link, but go to LearnElectrics.com and put P192 into the search bar and it comes up. Dave.

@bullohsemak8959 Год назад

Good day sir. May i ask tip for get resistance value for conductor from voltage drop table. Then i do continuity test i may know what the value show i get for good cable resistance for 10mter, 20mter and ect.

@learnelectrics4402 Год назад

You will get the cable resistances from table B1 in Gudance Note 3. Also take a look at this video on the attached link, thanks, Dave.... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Ax4-bZ7WDwg.html

@mohammadtahir5357 Год назад

Hei learn electrics Do you know any electrical accredited online course besides bs7671 18th edition?

@learnelectrics4402 Год назад

There are dozens of electrical courses Mohammad, You first need to decide what your career path is and then contact at least 3 local training centres and actually visit them and ask what courses they suggest. Visit, don't just telephone, you need to actually see what facilities they have. Do NOT, do NOT, do NOT hand over any money until you've seen three training centres and found one that you are happy with. Most centres are good, with motivated staff, its all down to what your intended career path is and how you feel about the centre when you visit. Good luck, its a good trade. Dave.
