How to calculate

~4ma/(human body) = soil of pants.

Stick a fork in it.

I don't believe that English is your first language. Perhaps you can reword this question somehow.

If you mean what is the soil's density right now, that's volume divided by weight.

If your talking about some electrical property, I don't know.

I am not sure what you mean either. Based on your previous posts, are you possibly talking about earthing?

Can you please re-write your post and include more information.

Hi, All

i am refering to the environment i.e

sulfuric acid -> 380,000 mA/m2

sea water -> 430,000 mA/m2

Soil - ??? mA/m2

is their a equation please

Soil resistivity depends on the soil composition. There is no single easy formula, however there are tables which give you values or ranges of values for different soil types, compositions and water content.

Please note that sulfuric acid and sea water also vary (ie- it is not a set value but a range depending on its concentration and mineral content).

Also try an internet search of soil resistivity. I know there are simple tables available somewhere on the internet.

Is this homework, because it looks like it? Come on. be honest.
