A voltage source is supplying a load through a long cable. The load is consuming 250 VA at 0.82 lagging power factor, and the voltage across it is 180 Vrms. The impedance of the cable is 5 + j4 9. a. The load may be modeled as an impedance consisting of a resistor in series with Choose one: a capacitor / an inductor. b. Draw the circuit that you can use to analyze the problem. Label all circuit elements and variables. c. Using the voltage across the load as the reference phasor, solve for the phasor current around the loop. d. What is the voltage (in rms) across the source? e. What is the real power delivered by the source?
