Question

define electric current and electric density class12 ​

Answer 1

Explanation:

Current density. Current density. Current density is defined as current flowing per unit area provided the area is held normal to the current. Current density is a property which describes at a specific point of the conductor.

thank you..

Answer 2

Answer:

In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. ... In SI base units, the electric current density is measured in amperes per square metre.Electric current is defined as the rate at which charge flows through a surface (the cross ... The unit of current density is the ampère per square meter , which has no special name.
