Current Density
Hilfe anzeigen
In this task, the conductor cross-section is required.
Think about how the formula for current density has to be rearranged.
If the current and the current density are given,
the required cross-sectional area can be calculated.

The given values are the
current of 25 A and the
current density of 5 A/mm².
The basic formula is:
current density = current divided by conductor cross-section.
The conductor cross-section is required.
Therefore, the formula is rearranged:
conductor cross-section = current divided by current density.
Substituting the values: 25 A ÷ 5 A/mm².
The calculation gives: 25 ÷ 5 = 5.
The required conductor cross-section is 5 mm².
A current of 25 A flows through a conductor.
The current density should be 5 A/mm².
What conductor cross-section is required?
