Consider the two loads in the circuit in (Figure 1). Load #1 (L1) absorbs S = 56 VA at a lagging power factor of pf = 0.61. Load #2 (L2) absorbs P2 = 56 W and Q2 = 1 VAR of power. If these loads are powered by a V = 425 V−rms , 60-Hz source, what impedance needs to be added to the circuit in order to raise the source's power factor to unity? Express your answer in rectangular...
Please answer question B Expert Q&A The design of any power transmission system is very sensitive to the magnitude of the current in the lines as determined by the applied loads. Increased current result in increased power losses in the transmission lines due to the resistance of the lines. Every effort must therefore be made to keep current levels at a minimum. The process of introducing reactive elements to bring the power factor closer to unity is called power factor...

VO) L1 L2 Line VO LI Power Calculations Learning Goal: In this tutorial, you will practice the calculation of power in circuits containing loads, including the effects of non-ideal transmission lines, and practice how to improve the power factor for an entire system. Many appliances (eg., hair dryers, coffee makers, and refrigerators) and industrial loads are powered by AC sources. The ability to be able to calculate their power needs is important in a number of situations. Before completing this...
