Experiment to determine the resistivity of a metal wire

This video shows the experimental procedure to measure current through, voltage across and diameter of sections of metal wire of known length. Current and voltage are used to determine the resistance.
Try the data analysis yourself, download a free worksheet here: physicshq.wixsite.com/alevelp...
Perfect if you're learning physics at home.
In video 2 ( • Experiment to Determin... ) the data is analysed and used to produce a resistance-length graph. And from that the resistivity of the metal is determined.
Electricity experiments, like this one, are mandatory practicals for many physics specifications. So this is good practice for OCR physics A, AQA A-Level physics, Edexcel A-Level physics, CPAC, PAG, practical endorsement.
Relevant concepts: electrical resistance, metal wire, resistivity, micrometer, and Ohm's law.

U man u really saved my future thanks a lot...much love to you

[@lommut8300]

Thanks man this is really helpful and clear!

[@jadkian1146]

helped with my homework for the practical tomorrow. Thanks!

[@MohaZF]

Nice vid!

[@jalalabuhijleh9591]

Do you have a list of materials that you have used in this demonstration, if so can you please reply and send it here thanks.

Niceeeee vid💎💎

One question, why did you use these current and voltage values? I mean, can these values ​​be generalized to any material?

[@ASh-qr2zq]

What should i do to obtain accurate values for L

[@potato8938]

may i ask, is there any procedure for this experiment?

[@anushkashinde7406]

Can I do this for steel?

[@mohammedarslan9684]

Is it alright if you can write down the method?

[@architagarwal7431]

what was the voltage that you supplied?

Not a great video to be honest, was hoping for some calculations.. not to watch you measure a wire for 7 minutes
