Assuming that a nonzero ac voltage source is applied, state whether the power and reactive power are positive, negative, or zero for a. a resistance in series with an inductance; b. a resistance in series with a capacitance. (Assume that the resistances, inductance, and capacitance are nonzero and finite in value.)

Consider an ac power circuit containing an ideal inductor. Determine the phase shift between the waveforms of the inductor voltage and current. Consider the inductor voltage as the reference. How does the resistance of the wire coil in an actual inductor affect the phase shift between the inductor voltage and current?

for a resistance and capicitance in a series with a voltage source, show that it is possible to draw a phasor diagram for the current and all voltages from magnitude measurment of these quantities only .illustrate your answer graphically

Determine period, frequency and rms value of the plotted current waveforms. 1 } ((A) ((A) PT ro) 1...4.. A+

. Determine the capacitance value that, when placed in parallel with this load, would produce a unity power factor. Assume that the source is 230 V at 60 Hz. The Q shown is a positive Inductive reactive power, which would have to be “offset” by the same value of Reactive Capacitance Power.
