What does temperature do to resistance? (44)

The effect temperature has on resistance is an age old problem. This week I'm fumbling about in the shed (and trying not to burn the place down) demonstrating what happens to a conductor when it gets hot and cold!

It's a simple experiment that involves using a blow torch! Who doesn't like using a blow torch?

The results are self evident, although I shall return with another example of cooling down a conductor.

Thanks for watching.

see you in the new shed!

Welcome back JBE, missed your videos, hope you are well mate.

Hi Beck nice to see you back. I think It would be better if you heated the copper wire itself not the insulation.

Nice to see you back. Upload more videos regularly. Looking forward to the videos of you building the new shed.

Welcome back James hopefully we will see some more videos from you

Great video, I was expecting the resistance to lower not go higher! Have missed your videos. Keep safe.

Very interesting video. Yes, please post the video of you building your new shed / workshop.

Great Experiment proving that the resistance of a conductor is proportional to: it's material' its length, it's Xsectional area and it's temperature.

Happy new year and its great to see you back on youtube :)

Decent little vid that 👍

Cool although this does lack the resistance in temperature with current flow so looking forward to more. Theoretically the resistance won't increase with a large load if the cable is Cooled it's the difference between overhead lines and buried conduit.

Be good if you could put the video up of you building the shed as I’m looking to do one my self 👍👍

Welcome bEck.

And here’s me thinking the knob was behind the blow torch not on the back of it 😀 it’s kind of a catch 22 situation isn’t it, a bad connection, or high resistance joint will get warmer, and in turn, the resistance will get even higher causing it to heat up even more 😂 lovely stuff !
