The resistivity is the indication of the electrical resistance of the matter.

However, the conductivity is an indication of the conductance of any matter.

This indicates that the matter having high conductivity allows passing current easily.

Also indicates that the matter having high resistivity does not allow passing current easily.

As the type of oil is not specified, the resistivity and conductivity can not be specified. However, it can be only compared as per the above behavior.

In day-to-day life, this has been observed that the current can not pass easily in oil as compared to that of water.

Thus, oil has high resistivity and low conductivity.

If $a,b,c\in (0,\mathrm{\infty})$ with abc=1 prove:

${a}^{2}+{b}^{2}+{c}^{2}+3(ab+bc+ca)\le \frac{1}{2}(\sqrt{a}+\sqrt{b}+\sqrt{c})(a+b)(b+c)(c+a).$

On atypical inequality (a smaller amount than a product) that resisted my attempts to prove it.

I know what resistivity of materials are like, and is given by the formula:

$R=\frac{\rho L}{A}$

However what is the volume resistivity of materials like copper and aluminium for instance? How do we calculate the volume resistivity of materials, because this was confusing when I read the site:

Method of calculating eddy currents of a conductor, is this correct?

Where there is the answer given by Floris states the equation:

$F=\frac{v\cdot {B}^{2}\cdot A}{\rho /t}$

Where $\rho $ is given to be the volume resisitivity.

My question:

how do we measure the volume resistivity of a material for example aluminium?

what happens if the thickness of the material changes?
