First, note that current does not normally flow through a capacitor, 1 so when we refer to "terminal current" for a capacitor, what we really mean is the flow of charge arriving or departing from one of the conductors via the circuit, which is equal to the flow of charge departing or arriving (respectively) at the other conductor. This gives the appearance of current flow through the ...
