Parts B and C.

Learning Goal: To use information about the power provided by a source or absorbed by a load to calculate average power, reactive power, apparent power, and the power factor. Before completing this tutorial, make sure you are familiar with the relationships between average, reactive, and apparent power and the power factor. Part A - Calculating average power, reactive power, and the power factor A load absorbs S = 18 kVA at a leading power factor of pf = 0.90. Use this information to calculate the average (P) and reactive (Q) power for the load. Enter comma separated numerical answers with three significant figures. ► View Available Hint(s) P, Q = 16.2,-7.85 kW, KVAR Submit Correct Term 2: Correct answer is shown. Your answer -7.846 kW, kVAR was either rounded differently or used a different number of significant figures than required for this part. Keep in mind that the power triangle requires that the average and reactive powers be numerically smaller in value than the apparent power Part B - Calculating apparent power and power factor A load operates at a voltage of V₂ = 100 V-rms and absorbs P = 70 W and Q = 37 VAR of power. Use this information to calculate the apparent power (S) and the power factor (pf) for the load.
