for displacement current?"
AC circuits can be completed by capacitance. Countless coupling
capacitors demonstrate a-c flow on and through conducting parts of a
circuit. The same current flows via displacement through the dielectric
which inhibits charge conduction.
AC current is the same through a series path but moving charges that
produce electric force may go only back and forth in very short paths.
Conduction causes displacement and vice versa.
