1. Next, this displacement current  is related to the charging of the capacitor. 2. :: : Be aware though that a displacement current  isn't a real current. 3. Some authors apply the name " displacement current  " to only this contribution. 4. This polarization is the displacement current  as it was originally conceived by Maxwell. 5. Substituting this form for in the expression for displacement current , it has two components: 6. If the condition is maintained sufficiently long, this displacement current  through the battery ceases. 7. Maxwell extended this view of displacement currents  in dielectrics to the ether of free space. 8. Some authors apply the name " displacement current  " to the first term by itself. 9. Maxwell's original explanation for displacement current  focused upon the situation that occurs in dielectric media. 10. There is also a displacement current  corresponding to the time-varying electric displacement field "'D " ':
