The current is required.
If the current density and the conductor cross-section are known,
the current density has to be multiplied by the conductor cross-section.
Make sure that the unit mm² cancels out in the calculation.

The given values are the current density of 3 A/mm² and
the conductor cross-section of 10 mm².
The basic formula is:
current density = current divided by conductor cross-section.
The current is required.
The rearranged formula is:
current = current density multiplied by conductor cross-section.
Substituting the values: 3 A/mm² × 10 mm².
The calculation gives: 3 × 10 = 30.
The current is 30 A.
A conductor has a cross-section of 10 mm².
The current density is 3 A/mm².
