A building with inductive loads has the average consumption of 40kW and 26kVAR. At the are location of the building, the electric utility applies a surcharge/additional payment (in %) based on the power factor of the load. A table has been used to determine the surcharge (shown in a separate photo). With the building supplied by a 230 Vrms source, solve for the following: a. The average current (in A rms) drawn by the building. b. Effective impedance of the building c. Surcharge or additional payment (in %) imposed on the building.
