WHAT IS R1+R2. How to change the values, what do they mean.

Have you ever wondered why electricians have this fascination for R1 and R2?
What is it? What does it mean?
Or perhaps you do know but you just need to understand it a little more and to be able to safely make changes to the resistance values of R1 and R2.
If you can get R1 and R2 right then everything else should fall into place.
The video asks - what can you do if you arrive at a property to carry out work and the Zs figures are already at a maximum and you need to extend the circuit?
It happens a lot, especially if the house was wired to 16th Edition or earlier.
The video shows how this can be achieved safely and in accordance with the Wiring Regulations.
Lots of answers and lots of solutions will be found in this Tech Tips video.

how i wish such learning resources had been available when i was an apprentice, and young electrician. it took me years to fully grasp what you teach so clearly and 40 years later i am still learning and getting better clarification from your videos

Thanks for making these videos, the amount of information that needs to be learned is daunting, but the way you explain things and break the subjects down makes it a lot easier to understand.

[lcutz]

There’s no other YouTube channel that breaks things down as well as you! Really appreciate these videos. Clear and concise making everything so clear to understand 👍 can’t wait to see this channel grow 👏

[martynlewis]

Excellent content. I’ve paid lots money to an electrical training company, I’m learning as much if not more by watching your videos. Thanks for this!

you have revolutionised teaching electrics without a doubt. So is basically the difference in energised and deenergised electrons is that energised electrons are buzzing with energy and they sell their buzz of energy to the load eg kettle etc and then the de energised electrons are vacant of energy ready to pick up their load of energy from the market ie the transformer and does all this happen extremely quickly. Thankyou for a great tutorial.

I love watching your videos, the way you explain things makes it so much easier to understand, far better than the tutors on my electrical course, please keep making these videos.

There are YouTube channels giving great insights into the industry. I am currently working towards my C&G level 2/3. I am finding this channel, Learn Electrics, to be the most useful in terms of knowledge and understanding; thanks for producing them and helping me to greatly develop my “mental toolbox”😊 …. Brilliant

[paulhayles]

I think you’ve a bit of a talent in explaining things..very well explained. Love the channel.

[slapman]

Really do not know how many ways I can say thank you for these videos, you're a legend.

[gillyg]

Without doubt the best learning videos about electrics on you tube. Thank you very much.

[persian_warrior]

Thank you again for the best explaining R1+R2

[qitvsjm]

You make it so easy. I learn so much from your videos, thanks.

[vx]

Thank you for your videos very helpful and clear. Please keep going, refresh our memory because of constant working no time for reading unfortunately .

Great great video. I love your channel.

At the risk of sounding like an idiot I'm a little confused when you said energised electricity flows through r1 and then de-energised energy flows through rn.

I never thought of it in this way and I'll have to look into that more.

Thanks a lot for taking the time to do these videos. Your teaching style works really well for me which is really saying something

[scarcxy]

Spot on, thank you so very much for this informative video. I like and love your videos, you make learning electricity so simple and understandable..

[Xxxcappie]

Best vids on the Internet are here! Thank you so much, please keep up the good work.

Last note: where can one find a greater range of breaker Zs permitted ranges. I'd like to keep them handy and printed out.

[MMG_MoonManGuitar]

Fantastic insight as usual. Thank you Dave and team 💪🏾
