Question

What Is Earth Resistance?

Answer 1

Earth resistance:

The resistance supplied by the earth's electrode toward the flow of electricity further into the surface or ground is characterized as earth resistance.

Mathematical representation:

Mathematically, earth resistance can be represented as:

$$\begin{gathered} \mathrm{Earth}\mathrm{resistance}=\frac{\mathrm{Potential}\mathrm{of}\mathrm{the}\mathrm{earth}\mathrm{electrode}}{\mathrm{Current}} \\ \mathrm{Earth}\mathrm{resistance}=\frac{\mathrm{V}}{\mathrm{I}} \end{gathered}$$

Here,

V is voltage.

I is current.

Therefore, the earth's resistance rises with depth as well as is temperature-dependent.
