Here are three circuits that are identical except for the frequency of the source. Capacitors "pass" higher frequencies more easily than lower ones. The higher the frequency of the lower circuit, the higher the current. This is because the voltage across a capacitor is proportional to the charge stored in it, and charge is the accumulation of current over time. With a shorter AC cycle, a higher current can flow for a shorter period of time and still result in the same peak charge (and therefore the same peak voltage).
