Electricity has become an essential part of our modern lives. We need electricity to light up the dark room and run all our appliances like fans, mixers, air conditioners, televisions, etc. In fact, we can not imagine a world without electricity. Electricity is referred to as a form of energy that results due to the flow of electrons. There are two kinds of electricity, namely, static electricity and current electricity. As the use of electricity is increasing nowadays, it is produced in large quantities and stored. Current is defined as the ra...

Defining CurrentWhat Are AC and DC current?Current Density DefinitionWhat Is The Current Density Formula?Current Density ExampleWhat Is The Unit of Current Density?Quick Exercise – 1What Is The Relation Between Current Density and Electric field?True Or False The SI unit of current density is Ampere/meter2. This unit also helps you remember the formula for calculation of such a density. Since Ampere is the unit of current and meter2 is the unit for measuring cross-sectional area, one can easily derive the formula for current density. It is the current flow divided by the area of the cross section.

Here are all the possible meanings and translations of the word current density. In electromagnetism, and related fields in solid state physics, condensed matter physics etc. current density is the electric current per unit area of cross section. It is defined as a vector whose magnitude is the electric current per cross-sectional area.
