Γραμμή 2:
Displacement current is a quantity related to changing [[electric field]]. It occurs in [[dielectric]] materials and also in free space.
In the particular case of when it occurs in free space, it is not believed to involve the motion of electric charge as is the case with free electric current and
Displacement current possesses the units of electric current and it has an associated changing [[magnetic field]]. It appears in [[James Clerk Maxwell]]'s 1861 paper entitled [http://vacuum-physics.com/Maxwell/maxwell_oplf.pdf On Physical Lines of Force].
