Displacement current in charging capacitor [duplicate]
When you consider a loop encircling the wire, you have an electrical field only in the wire. And in the wire this field produces exactly the same total (mainly conduction) current as the displacement current in the capacitor. If you want to be nitpicky, you also have displacement current in the wire when there is a changing electric field.
