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 in the blank fields with the apparent power, active power, and reactive power of the previous system:
