How to Calculate and Solve for Electron Mobility of Metal | Electrical Properties
Last Updated on August 11, 2022
The image of electron mobility of metal is shown below.
To compute for electron mobility of metal, two essential parameters are needed and these parameters are Hall Coefficient (RH) and Electrical Conductivity (σ).
The formula for calculating electron mobiltiy of metal:
μe = |RH|σ
Where:
μe = Electron Mobility of Metals
RH = Hall Coefficient
σ = Electrical Conductivity
Let’s solve an example;
Find the electron mobility of metal when the hall coefficient is 28 and the electrical conductivity is 7.
This implies that;
RH = Hall Coefficient = 28
σ = Electrical Conductivity = 7
μe = |RH|σ
μe = |28|(7)
μe = (28)(7)
μe = 196
Therefore, the electron mobility of metals is 196 m²/(V.s).
Calculating the Hall Coefficient when the Electron Mobility of Metals and the Electrical Conductivity is Given.
RH = μe / σ
Where:
RH = Hall Coefficient
μe = Electron Mobility of Metals
σ = Electrical Conductivity
Let’s solve an example;
Find the hall coefficient when the electron mobility of metals is 24 and the electrical conductivity is 12.
This implies that;
μe = Electron Mobility of Metals = 24
σ = Electrical Conductivity = 12
RH = μe / σ
RH = 24 / 12
RH = 2
Therefore, the hall coefficient is 2.
Calculating the Electrical Conductivity when the Electron Mobility of Metals and the Hall Coefficient is Given.
σ = μe / RH
Where:
σ = Electrical Conductivity
μe = Electron Mobility of Metals
RH = Hall Coefficient
Let’s solve an example;
Find the electrical conductivity when the electron mobility of metals is 48 and the hall coefficient is 12.
This implies that;
μe = Electron Mobility of Metals = 48
RH = Hall Coefficient = 12
σ = μe / RH
σ = 48 / 12
σ = 4
Therefore, the electrical conductivity is 4.
