How to Calculate and Solve for Current Density | Electrical Properties

The current density is illustrated by the image below. To calculate 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
That is, j = (32)(4)
j = 128

Therefore, the current density is 128 A/m².
