1. Determine the power factor for the following system:
Load 1: VAR (L), W Load 2: VAR (C), W Load 3: VAR (L), W
2. For the illustrated system, find the current \(I\):
Load 1: VAR (L), W Load 2: VAR (L), W Load 3: VAR (C), W Load 4: VAR (C), W
3. The loading of a factory on a 1000 V, 60 Hz system includes kW heating (unity power factor), kW induction motors (0.7 lagging power factor), and kW lighting (0.85 lagging power factor); What is the required capacitor to raise the power factor to unity?
4. Fill the blank fields with the apparent power, active power, and reactive power of the previous system:
