RING CIRCUIT CALCULATIONS - TESTING METHODS AND SOME PROBLEMS - THE RIGHT NUMBERS AND THE WRONG ONES

This video is about ring circuit testing and the calculations. As well as the correct way to understand the calculations we will also show you some of the problems that may be encountered during the testing process. We also hope to show you how to recognise what are good readings and which numbers are the wrong ones.
Many times over many years, people have told us at Learn Electrics that they know how to test a ring circuit, but they are never sure of the numbers, where the numbers come from and why it is so important to know what R1 plus R2 should be.
And then, how do we measure it, can we calculate it, and why divide by 4, what is all that about.
So we will look at what good readings should be and how to calculate them and then look at some wrong readings for a ring circuit test. How do you know when the numbers just don’t add up.
This video is No.143 on our RUclips channel where we have videos on a wide range of electrical topics.

Excellent content! I've recently qualified and sometimes scratch your head to remember what you have learnt in the classroom. Such a great recap and reassurance you are doing it right!

[@learnelectrics4402]

Great to know that you enjoyed it. We all need reminders from time to time. I've been in the trade for over 40 years and still learning. Dave.

Great comment. Thanks for watching. Dave.

Forgot to mention, will you be doing any videos on electrical science and principles dave ?👍

[@ionelinzona]

Please do some videos with electrical science

[@learnelectrics4402]

It is now on the list to do. Thanks for the request. Dave.

[@learnelectrics4402]

Yes, we have added this to the list. Thanks for supporting the channel. Dave.

[@sm8899]

HELLO SIR CAN YOU PLEASE MAKE ONE VIDEO ON LIGHTING CIRCUIT TESTING..I CANT FIND ANY ON YOUR CHANNEL VIDEOS.THANKS IN ADVANCE YOUR VIDEOS ALWAYS BEEN VERY VERY HELPFUL AS A STUDENT OF ELECTRICAL.

[@learnelectrics4402]

I will put it on the list. Thanks for asking. Dave.

[@drpantastic1969]

I thought you might of covered iterconnetions also ring within a ring scenario

[@learnelectrics4402]

Now that's a good idea. I'll put it on the list. Thanks for watching. Dave.

[@zu1875lu]

I've got tbh here. This to me is very confusing. All these comments of 'so simple, brilliantly explained, how do you do it!!!' I'm calling bs. No way is this that easy. I'll go over it till it sticks... but pls stop with the drivel.

[@learnelectrics4402]

Thanks for watching.

[@we-are-electric1445]

At 13:11 Maybe I need my eyes testing but it looks like the bottom two rows on the Table for S2 have been inadvertently interchanged

[@learnelectrics4402]

Eyes are fine. Yes, a case of juggling too many numbers. Massive thanks for the info, really appreciated and thanks for watching. Dave.
