current density

noun

, Electricity.

1. 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

noun

1. 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

Example Sentences

The paper battery achieved an open circuit voltage of 1.8 volts, a 1.0 volt current density of 100 mA/cm², and a maximum output of 103 milliwatts/cm².

From Science Daily

The new study shows indium has two crucial characteristics as a battery anode: an extremely low migration energy barrier, which sets the rate at which ions diffuse in the solid state; and a modest exchange current density, which is related to the rate at which ions are reduced in the anode.

From Science Daily

These coated particles create a homogenous surface across which the current density is evenly distributed, preventing the growth of dendrites.

From Science Daily

Upon carrying out electrocatalytic water splitting, the team observed that Ni-W5N4 alloy catalyzed the hydrogen evolution reaction, resulting in 10 mA/cm2 current density at a small overpotential of 11 mV.

From Science Daily

It showed a remarkable current density of 100 mA/cm2 at an overpotential of just 230 mV.
