Current density describes the load on the conductor cross-section.
Divide the current by the cross-section.
The larger the cross-section is for the same current,
the lower the current density becomes.

The given values are the current of 18 A and
the conductor cross-section of 6 mm².
The formula is:
current density = current divided by conductor cross-section.
Substituting the values: 18 A ÷ 6 mm².
The calculation gives: 18 ÷ 6 = 3.
The current density is 3 A/mm².
A current of 18 A
flows through a conductor with a cross-section of 6 mm².
What is the current density?
