Assume that an industrial plant can be represented by a series combination of a 40 resistor, a 5mF capacitor, and a 20mH inductor, that is connected to an AC supply of v5 = 50 cos(200t) V as shown in Figure A3. Using phasor representation, find a) The equivalent impedance of the plant, in cartesian and in polar forms, b) The RMS value of the current drawn by the plant from the voltage supply c) The apparent power of the plant d) The real power of the plant e) The reactive power of the plant. 452 1 5 mF 20 mH

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.…
