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...
