The amount of electric current travelling per unit cross-section area is called as current density and expressed in amperes per square meter. More the current in a conductor, higher will be the current density. However, the current density alters in different parts of an electrical conductor and the effect takes place with alternating currents at higher frequencies.
Electric current always creates a magnetic field. Stronger the current, more intense is the magnetic field. Varying AC or DC creates an electromagnetic field and this is the principle based on which signal propagation takes place.
The formula for Current Density is given as,
J = I / A
Where,
I = current flowing through the conductor in Amperes
A = cross sectional area in m2.
Current density is expressed in A/m2.
