current density

noun

, Electricity.

the amount of current flowing through a given cross-sectional area in a given time interval: usually measured in amperes per square centimeter.

current density

the ratio of the electric current flowing at a particular point in a conductor to the cross-sectional area of the conductor taken perpendicular to the current flow at that point. It is measured in amperes per square metre J

The dependence of the mechanical qualities of the copper upon the current-density employed is well known.

He thus achieved a high current-density and much greater beam intensities.
