How to Calculate and Solve for Total Resistivity of Metal | Electrical Properties

Last Updated on August 9, 2022

The total resistivity of metal is illustrated by the image below.

To compute for total resistivity of metal, three essential parameters are needed and these parameters are Thermal Resistivity (ρt), Impurity Resistivity (ρi) and Deformation Resistivity (ρd).

The formula for calculating the total resistivity of metal:

ρtotal = ρt + ρi + ρd

Where:

ρtotal = Total Resistivity of Metal
ρt = Thermal Resistivity
ρi = Impurity Resistivity
ρd = Deformation Resistivity

Let’s solve an example;
Find the total resistivity of metal when the thermal resistivity is 20, the impurity resistivity is 10 and the deformation resistivity is 2.

This implies that;

ρt = Thermal Resistivity = 20
ρi = Impurity Resistivity = 10
ρd = Deformation Resistivity = 2

ρtotal = ρt + ρi + ρd
ρtotal = 20 + 10 + 2
ρtotal = 32

Therefore, the total resistivity of metal is 32 Ω-m.

Calculating the Thermal Resistivity when the Total Resistivity of Metal, the Impurity Resistivity and the Deformation Resistivity is Given.

ρt = ρtotal – ρi – ρd

Where:

ρt = Thermal Resistivity
ρtotal = Total Resistivity of Metal
ρi = Impurity Resistivity
ρd = Deformation Resistivity

Let’s solve an example;
Find the thermal resistivity when the total resistivity of metal is 40, the impurity resistivity is 10 and the deformation resistivity is 5.

This implies that;

ρtotal = Total Resistivity of Metal = 40
ρi = Impurity Resistivity = 10
ρd = Deformation Resistivity = 5

ρt = ρtotal – ρi – ρd
ρt = 40 – 10 – 5
ρt = 25

Therefore, the thermal resistivity is 25.

Calculating  the Impurity Resistivity when the Total Resistivity of Metal, the Thermal Resistivity and the Deformation Resistivity is Given.

ρi = ρtotal – ρt – ρd

Where:

ρi = Impurity Resistivity
ρtotal = Total Resistivity of Metal
ρt = Thermal Resistivity
ρd = Deformation Resistivity

Let’s solve an example;
Find the impurity resistivity when the total resistivity of metal is 28, the thermal resistivity is 12 and the deformation resistivity is 2.

This implies that;

ρtotal = Total Resistivity of Metal = 28
ρt = Thermal Resistivity = 12
ρd = Deformation Resistivity = 2

ρi = ρtotal – ρt – ρd
ρi = 28 – 12 – 2
ρi = 14

Therefore, the impurity resistivity is 14.

Calculating the Deformation Resistivity when the Total Resistivity of Metal, the Thermal Resistivity and the Impurity Resistivity is Given.

ρd = ρtotal – ρt – ρi

Where:

ρd = Deformation Resistivity
ρtotal = Total Resistivity of Metal
ρt = Thermal Resistivity
ρi = Impurity Resistivity

Let’s solve an example;
Find the deformation resistivity when the total resistivity of metal is 52, the thermal resistivity is 24 and the impurity resistivity is 10.

This implies that;

ρtotal = Total Resistivity of Metal = 52
ρt = Thermal Resistivity = 24
ρi = Impurity Resistivity = 10

ρd = ρtotal – ρt – ρi
ρd = 52 – 24 – 10
ρd = 18

Therefore, the deformation resistivity is 18.
