Find the average power, P, and the reactive power, Q for each element in the following circuit. (Ignore Vx). 2. A system consists of a single source with a voltage of 100 V rms connected to 3 loads, where load 1 absorbs 10kW at PF=0.2 lagging, load 2 absorbs 8 35º kVA, and load 3 has a current magnitude of 25 Arms at PF=0.4 lagging. a) What are the load impedances and the load currents? b) What is the total source current, I S ? c) What is the real power delivered by the source? d) What is the complex power absorbed by the 3 loads combined? e) What is the power factor of the three loads combined? f) To increase the power factor to 0.95 lagging, without changing the real power
