The power dissipation is proportional to the square of the current flowing through the capacitor, and is therefore proportional to the square of the applied voltage.<\/p>\n<p>The operating frequency of a capacitor is the frequency of the alternating current (AC) voltage that is applied to the capacitor. The power dissipation of a capacitor increases with increasing operating frequency because the current flowing through the capacitor increases with increasing frequency.<\/p>\n<p>The following are the explanations for each option:<\/p>\n<ul>\n<li>Option A: Power dissipation of a pure capacitor increases with operating frequency. This is because the current flowing through the capacitor increases with increasing frequency, and the power dissipation is proportional to the square of the current.<\/li>\n<li>Option B: Power dissipation of a pure capacitor decreases with operating frequency. This is not true, as the power dissipation increases with increasing frequency.<\/li>\n<li>Option C: There is no meaningful relationship between the power dissipation of a pure capacitor and its operating frequency. This is not true, as the power dissipation is proportional to the square of the current, which is in turn proportional to the frequency.<\/li>\n<li>Option D: All of the above. This is not true, as only option A is correct.<\/li>\n<li>Option E: None of the above.
