Hey guys,

Doing an AS Physics Planning Excercise where i have to design an experiment to find the resistivity of paper.

But the thing is to check my results, i need to know the actual true value for the resistivity of paper (in Ohm metres) but cant for the life of me find it, anywhere.

Anyone here happen to know?!

Karma for a week (yes a whole 7 days) for the answer!

Thanks

Does paper conduct electricity? lol, I learn something new every day.

Volts / Amperage = Ohms.

Put an electric charge through paper and find out the voltage and amperage, divide the voltage with the amount of amperage?

got a multi meter? paper is a good resistor so its going to be high you could try forcing current through the paper to see when it catches on fire, but that would depend on the thickness of the paper

...Shouldn't your teacher have given you that info?

i beleive this is what you are looking for. i'm not much of an electrical person, but the experiment sounds right, provided you have the materials.

beat you to it! im sure the resistance of paper coefficient is published somewhere though

yeah, most likely in a website where you need specific access to, and may have to pay for.

Damn, I don't remember from when I did that. Props for taking Physics, though.

PBAsydney - I am doing that experiment to find my own values, but i need some correct values to check my ones against.

Locoloki- See above.

Hurricane - He said to "research" it. grrrr

As for http://physics.nku.edu/GeneralLab/211%2 … t-ppr.html ive seen that site before, but didnt see any specific vales, just the experiement im doing. ill have another look.

Good response so far though...

You could try this site.

It might have paper on.

My physics teacher has a big book at school of the resistivity of like...everything, that's what we used for our coursework.

But yeah...it's at school.

Trust your experiment right?!

You know the name of the book? My teacher said the info was a massive book like that, but never gave the name. Might have to go to that scary library *shudders*

No idea sorry. But it's massive, and old, and heavy...ooooo, and brown!

That would only give the resistance of the paper you passed it through. The resistivity is slightly different.

For example thicker gauge copper wire has a lower resistance than thin copper wire, yet the resistivity of the matierial is the same.

^^^

Joo are clever.

Yes resistivity is a constant for a material, that is depend on a few factors such as atomic sturcutre / arrangement in the material, while resistance can vary.

Edit: But i can find the RESISTANCE using V=I/R and with a forumla find the resistivity.
