The parallel arrangement produces a well balanced transmission circuit that has very low sensitivity to faraway interference resources including lightning.
Just one frequent reason for interference is purely natural electrical disturbances which include lightning or auroras; A different is cross communicate, an unwelcome transferral of signals from one particular circuit to a different owing to inductive coupling concerning two or maybe more intently spaced wire traces.
By enclosing just one conducting wire in the dielectric insulator and an outer conducting shell, an electrically shielded transmission circuit identified as coaxial cable is obtained. In the coaxial cable the electromagnetic field propagates throughout the dielectric insulator, although the associated current flow is restricted to adjacent surfaces of the interior and outer conductors.
