How to Calculate and Solve for Current Density | Electrical Properties
Last Updated on August 9, 2022
The current density is illustrated by the image below.
To compute for current density, two essential parameters are needed and the parameters are Electrical Conductivity (σ) and Electric Field Intensity (E).
The formula for calculating current density:
j = σE
Where:
j = Current Density
σ = Electrical Conductivity
E = Electric Field Intensity
Let’s solve an example;
Find the current density when the electrical conductivity is 32 and the electric field intensity is 4.
This implies that;
σ = Electrical Conductivity = 32
E = Electric Field Intensity = 4
j = σE
j = (32)(4)
j = 128
Therefore, the current density is 128 A/m².
