The image above represents depth of penetration. To compute for depth of penetration, two essential parameters are needed and these parameters are Conductivity (σ) and frequency (f).
The formula for calculating for depth of penetration:
d = 503.8 / √(σf)
Where:
d = Depth of Penetration
σ = Conductivity
f = Frequency
Let’s solve an example;
Find the depth of penetration when the conductivity is 12 and the frequency is 24.
This implies that;
σ = Conductivity = 12
f = Frequency = 24
d = 503.8 / √(σf)
d = 503.8 / √(12(24))
So, d = 503.8 / √(288)
d =Â 503.8Â /Â 16.97
d = 29.68
Therefore, the depth of penetration is 29.68.

Let’s solve an example;
Find the conductivity when the depth of penetration is 20 and the frequency is 15.
This implies that;
d = Depth of Penetration = 20
f = Frequency = 15
σ = (503.8 / d)2 / f
σ = (503.8 / 20)2 / 15
That is, σ = (25.19)2 / 15
σ = 634.53 / 15
σ = 42.30
Therefore, the conductivity is 42.30.

Calculating the Frequency when the Depth of Penetration and the Conductivity are Given
f = (503.8 / d)2 / σ
Where;
f = Frequency
d = Depth of Penetration
σ = Conductivity
Let’s solve an example;
Find the frequency when the depth of penetration is 32 and the conductivity is 10.
This implies that;
d = Depth of Penetration = 32
σ = Conductivity = 10
f = (503.8 / d)2 / σ
f = (503.8 / 32)2 / 10
So, f = (15.74)2 / 10
f = 247.8 / 10
f = 24.78
Therefore, the frequency is 24.78.
