Actually, a capacitor only appears to pass AC voltages. Internally there are two plates separated by a dielectric (insulator). So by the nature of its design can't pass any voltage. It can however store a voltage. There is a long winded electical/mathmatical explanation for this if anyone cares to look into the nature of alternating current and capacitance.
