I'm doing coursework on resistance and i've done all of the experiments and what not but i'm stuck on what to put on the introduction as we have to put some background information on resistance and how it works ect.
I've put a basic description of what resistance is and the formula for it but I need some more information.
Why does the Voltage divided by the current equal the resistance?
What does resistance effect in real life?
I need to know things like that.

a^(log_a(2/x)+log_a(x))

That is all the log stuff as a power of a....! Yikes
Thanks for ccleaer steps on this one. I know it probably is easier than I think BUT likely not.

For an experimant I did at school, I have to columns of data A & B, all the numbers in 1 of the columns represent multiple trials of the same experimental condition. Thus, there are two different conditions. I want to prove that there is a significant difference between the two experimental conditions to say less than 5%. What test should I use for this?

I am a little confused as to how toxic is mercury ? I am interested in a factual answer to this question as I have heard of mad people snorting mercury and handling mercury and those people are still alive, where as mercury is always described as being a very toxic substance.
http://www.zyra.org.uk/mercury3.htm
This website shows someone holding mercury in the palm of his hand where as other websites says that only a very small amout of mercury like a few small drops is enough to kill you.
Please can you give sensable answer to this question.

I have an ohmsmeter that i borrowed from my school to measure resistance. I set it to 20 k. I want to know what unit the K stands for and how i should write the final measurement. Also i want to change resistance to conductivity. Do you know what the conversion factor is and can you give me an example. Say when set to 20k it measures .22. what will the conductivity be. Also right it with the appropriate units.

THanks very very much
