It does seem like an odd question doesn't it. Why would anyone need the resistance of a brick, at any temperature. I don't know and i'm a physicist. Does anyone that is doing this 'brick resistance' thing know if there are any practical uses to this experiment, past having to do it for coursework.

Do you know something?  I'm fairly new to answerbank, and even I'M sick to death of this question. 

Am I right in thinking that kids just ask people to do their homework for them, without so much as rephrasing the question, or even saying please or thank you?

Don't even get me started on them not using the search facility.  It's not computer illiteracy, it's bone idleness.

Anyway, sorry for rant.  Continue.

I'm a mature student - and originally trained as a science teacher (but without the physics bit) and I'm completely baffled by this question.  I don't want someone to answer it for me - although that would be nice :) but I would like pointing in the right direction by people in the 'know'.  I've tried every website I can think of and four libraries and the information is not really much use (putting it politely).  Forums like this give people the chance to try and get ideas and yet the actual work they produce will still be their own.  So come on, those of you out there laughing at those of us who can't do this - share your knowledge - please.

It seems like an exercise in thinking through the logistics of the experiment rather than the value of the results.

How do you heat it, how do you measure the resistance, what practical problem would arise and how would you overcome them.

Do you actually need to do this, or just plan it?

We only need to plan it - and we're supposed to use typical 'school' laboratory equipment! (ha ha)

ok i will share my knowledge on this subject - look to the bottom left of the screen and you will see a catagory search option, search the science section with the word BRICK this will show you all the other questions your colleagues have asked - i will admit that a lot of the are just people like us saying STOP ASKING THIS STUPID QUESTION but if you click through them all you will indeed find that the first 5 or  6 times people give their time and energy to help discuss how this would be done... I am not going to do this for you however, so please put this small amount of work into your research as you cannot ask people to do absolutely everything for you. Good luck with your experiment, and if you feel you have got something out of the site why not add an answer or two regarding brick resistance once you have answered your project

Hi sorry to bring this question up again but I have been doing some reasearch on the internet and I was wondering if it would be possible to put the brick in a kiln to heat it up and use an infrared thermometer to measure the temperature of the brick from a window in the kiln?? That way I won't have the complications of a thermocouple to deal with??

ANY IDEAS
