[amp_mcq option1=”Power dissipation of a pure capacitor increases with operating frequency” option2=”Power dissipation of a pure capacitor decreases with operating frequency” option3=”There is no meaningful relationship between the power dissipation of a pure capacitor and its operating frequency” option4=”All of the above E. None of the above” correct=”option1″]<\/p>\n

The correct answer is: A. Power dissipation of a pure capacitor increases with operating frequency.<\/strong><\/p>\n

A capacitor is a passive two-terminal electrical component used to store energy in an electric field. The physical construction of a capacitor can be very simple, consisting of two conducting plates separated by an insulating material. The capacitance of a capacitor is measured in farads (F), and is proportional to the area of the plates and inversely proportional to the distance between them.<\/p>\n

The power dissipation of a capacitor is the rate at which energy is lost in the capacitor due to the resistance of the conductors and the dielectric material. 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

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

The following are the explanations for each option:<\/p>\n
