@bigjosh what book are you talking about that is for high school students?

comment Material with fairly high resistivity, but allows flow of charge
Thanks again. Any ideas how would I choose/construct materials which maximise 'resistance' (not necessarily resistivity), but minimizes discharge time?

comment Material with fairly high resistivity, but allows flow of charge
does discharge time depend on contact surface area at all?

comment Material with fairly high resistivity, but allows flow of charge
What about for more complicated objects? Something involving integrals perhaps

comment Material with fairly high resistivity, but allows flow of charge
Thanks, I am satisfied with your answer. One last thing, could you point me to a formula for resistance? I would like to see all the factors that affect resistance

I think I understand what you're saying, but I think capacitance may be the concept I'm looking for. I forgot everything I learnt about it though

Regarding your first paragraph, could you point me to the exact formula?

comment Material with fairly high resistivity, but allows flow of charge
My bad, I 'calculated' the resistivity based on the data sheet and it was the same to a high level of accuracy. However you seem to imply that the method of measuring resistivity is to time loss of charge. I did not know that.

Thanks for the comments. How exactly does capacitance play into all this?

comment Material with fairly high resistivity, but allows flow of charge
Thanks for the response. I'm going to need to refresh my memory on capacitance and get back to you
May

comment Material with fairly high resistivity, but allows flow of charge
Thanks for the response. But I measured the resistivity of both and it was the same

What parts are you unclear about exactly? I wish to discharge static electricity via a material that can also block current (i.e. has high resistivity).
