- This first in a series of videos will show you by means of a practical experiment how changing length and cross sectional area of a conductor affects the resistance of the conductor. This is a good way to develop your understanding of circuits at all levels of study involving electrical science.

Wow another fantastic science and principles resource 👍
Thanks for the support Gaz!
Another quality video Joe! Great explanation showing how theory is relevant to practical in the real world. Think it's easier for people, students etc, etc to pick up when it is shown in action rather than written on a board and just talked about. This way you are literally shown the relevance.
Thanks for the feedback Craig, I think it's important to always highlight the application of the principles back to the real world so you can see the point of it. A follow up video will be launched this week so stay tuned!
Agreed
very good bro..
love from india 🇮🇳 ♥️
god bless you..bro..😊😊
Excellent video !!!
Clearly and professionally explained.
Well done!
Many thanks
My absolute pleasure, glad it helped. 😁
Excellent practical demonstration which gives clear insight.
Great Video, thanks Joe!
Another great video thank you Joe
Great video, helpful practical example of resistance in cables and how lengths and csa are linked. Very helpful learning aid for a visual Learner like me in my college studies 👍🏻
Thanks for the nice comment David, the next in this series should be interesting viewing, stay tuned!
This is exactly what I was looking for.
Thank you
My pleasure! 😊
Interesting stuff.
Yup using this for my physics class tomorrow awesome vid love the beats dropped too
Ta Joe .. your demonstrations are SUCH a good way of facilitating understanding and retention 👍
Glad it helps Linda!
Thankyou so much joe!
Thank you for fantastic experiment and great explanation
My pleasure, glad you enjoyed it!
this is inspiring
Good stuff. Keep it up pal
Thanks Jamie, I will.
Super
Please what is the other name for the multi-function tester
You explain things better than my physics professor
That's very kind of you to say, thanks very much. Let your classmates know! Maybe not your professor though...
What about resistivity?
Can you tell me the procedures
i dont have any idea about how the numbers effect it so im just asking a question, if i take two phone chargers that are same in every way but one of them is 2 meters and the other is 1 meter, would it have any difference like a minute or two while fully charging or will it has an inconceivable effect?
If it's a dumb charger that doesn't respond to the charging rate of the phone there would be a a very small amount of difference in current flowing into the phone which could change the charge time, but the difference would likely be very small. 👍
Hi.
Any video in the relationship between temperature of the conductor and resistance?
Hi, search CZcams for "Joe Robinson Training resistivity" or click the link below:

@@JoeRobinsonTraining thank you. Great videos.
⭐️⭐️⭐️⭐️⭐️👍🏻
does surface area affect the resistance because the heat is better handled?
What do you mean joe 1:36 ?
It's awful to unreel cable when the end falls off the drum.
Just one quiitisisum why are referring to the earth conductor as the CPC stop it, it is and always has been the earth conductor and always will be same as the cable it has always been cald flat twin and earth if you buy a drum of cable from the supplier the label on that drum reads for example 2.5mm2 flat twin and earth followed by the BS number. It does not read pvc pvc twin and cpc, Sorry to be picky
Great question Sean, there is a really good reason for it and I'm planning a video to explain why. You can get a head start by looking at the definition of "Earth" in BS 7671. 👍
