    Current in the capacitor increases as the frequency of the generator increases

    Explanation:

    Xc = 1/2πfC = 1 / wC

    Since frequency is inversely proportional to reactance of a capacitor,

    as the frequency increases, the capacitance decreases and tend towards behaving like a wire with zero resistance as such the generator send high current to the capacitor, the current in the capacitor increases.
