Problem #7) Specify whether each of the statements are TRUE or FALSE. D Reactive Power is a measure of the average power consumed by reactive (capacitive and inductive) loads. When connected to an AC voltage source, the instantaneous power (rate of energy transfer) supplied to a resistor varies at a frequency that is 2x the frequency of the applied source voltage. The magnitude of the impedance of a capacitor supplied by an AC source will increase as the source frequency increases. An AC source that has an RMS magnitude of 100V will supply the same average power to a resistor compared to a 100V DC source. The voltage across a capacitor is proportional to the rate of change of the current flowing through the capacitor. The magnitude of the impedance of a resistor supplied by an AC source does not vary as the source frequency increases. A complex impedance Z=R+jX, that has non-zero resistive and reactive components, will consume both real and reactive power when supplied by an AC source.…
