The SI unit of electric current is the ampere (A), which is equal to a flow of one coulomb of charge per second In solid conductive metal, a large population of electrons are mobile or free electrons.lectric current is the flow (movement) of electric charge. The SI unit of electric current is the ampere (A), which is equal to a flow of one coulomb of charge per second. God_Of_War Â· 8 years ago. Thumbs up.
In electromagnetism, 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 at a given point in space (i.e. it is a vector field).In SI units, the electric current density is measured in amperes per square metre.lectric current density J is simply the electric current I (SI unit: A) per unit area A (SI unit: m 2). Its magnitude is given by the limit :
