Current Flow in a Capacitor

The charges seem to flow around the circuit, but do you think they flow through the dielectric (insulator)?

The answer is no. However, charges are moving onto one plate and off the other plate. An explanation to this question comes through the study of electric field E and considers a changing in electric displacement density D to be the equivalent of current. The more rapidly D changes, the more current flows. This current is called a displacement current. The larger the capacitor, the greater the current.
