Calculate the current density through a conductor given the current and cross-sectional area. Current density helps assess whether a conductor can handle the current without overheating.
Enter your values below
Current flowing through the conductor.
Cross-sectional area of the conductor in square millimeters.
How this calculator works
Current density J is the electric current I per unit cross-sectional area A of the conductor. It is a vector quantity measured in A/m^2.
