How to Calculate and Solve for Relationship between Thermal Resistivity and Temperature | Electrical Properties
Last Updated on August 9, 2022
The relationship betweeen thermal resistivity and temperature is illustrated by the image below.
To compute for the relationship between thermal resistivity and temperature, three essential parameters are needed and these parameters are Constant of the Metal (a), Constant of the Metal (ρo) and Temperature (T).
The formula for calculating relationship between thermal resistivity and temperature:
ρt = ρo + aT
Where:
ρt = Thermal Resistivity
ρo = Constant of the Metal
a = Constant of the Metal
T = Temperature
Let’s solve an example;
Find the relationship between thermal resistivity and temperature when the constant of the metal is 32, the constant of the metal is 8 and the temperature is 2.
This implies that;
ρo = Constant of the Metal = 32
a = Constant of the Metal = 8
T = Temperature = 2
ρt = ρo + aT
ρt = 32 + (8)(2)
ρt = 32 + (16)
ρt = 48
Therefore, the relationship between thermal resistivity and temperature is 48 Ωm.
Calculating the Constant of the Metal when the Relationship between Thermal Resistivity and Temperature, the Constant of the Metal and the Temperature is Given.
ρo = ρt – aT
Where:
ρo = Constant of the Metal
ρt = Thermal Resistivity
a = Constant of the Metal
T = Temperature
Let’s solve an example;
Find the constant of the metal when the thermal resistivity is 32, the constant of the metal is 2 and the temperature is 4.
This implies that;
ρt = Thermal Resistivity = 32
a = Constant of the Metal = 2
T = Temperature = 4
ρo = ρt – aT
ρo = 32 – 2(4)
ρo = 32 – 8
ρo = 24
Therefore, the constant of the metal is 24.
Calculating the Temperature when the Relationship between Thermal Resistivity and Temperature, the Constant of the Metal and the Constant of the Metal is Given.
T = ρt – ρo / a
Where:
T = Temperature
ρt = Thermal Resistivity
ρo = Constant of the Metal
a = Constant of the Metal
Let’s solve an example;
Find the temperature when the thermal resistivity is 42, the constant of the metal is 20 and the constant of the metal is 11.
This implies that;
ρt = Thermal Resistivity = 42
ρo = Constant of the Metal = 20
a = Constant of the Metal = 11
T = ρt – ρo / a
T = 42 – 20 / 11
T = 22 / 11
T = 2
Therefore, the temperature is 2.
