congrats on reading the definition of Current Density. now let's actually learn it.
Electric Field: The force per unit charge experienced by a charged particle in an electric field.
Ampere's Law: Relates the magnetic field around a closed loop to the electric current passing through that loop.
Conductors and Insulators: Materials that allow or resist the flow of electric current, respectively.
