Current Density
Definition
Current density refers to the amount of electric current flowing through a given area. It is calculated by dividing the magnitude of the current by the cross-sectional area it passes through.
Related terms
Resistivity: Resistivity is a property of materials that determines how strongly they resist electric current flow. It depends on factors like temperature and material composition.
Electric Field: Electric field refers to an invisible force field created by electric charges. It exerts a force on other charges within its vicinity.
Ampere's Law: Ampere's law relates magnetic fields to electric currents. It states that magnetic fields are generated around closed loops when there is an electric current flowing through them.
