cinderella1 Posted August 7, 2011 Report Posted August 7, 2011 Q: A 60Hz, 120V ac source supplies a group of loads as shown in Figure. If the voltage source is Vs=120V, find the apparent power of the source and the current Is.capacitor is connected parallel with load 1 and also parallel with load 2.connecting wire dissipates 1kW.load 1: 50kW with pf=0.7 laggingload 2: 20kW with pf=0.8 laggingcapacitor: 30kVAR Quote
