2. Three series loads are drawing 20A ms current through a 60Hz source. Load 1 is an 400W, 0.8 lagging induction motor. Load 2 is a 500VA, 0.6 lagging power factor and load 3 is a 2 ohm incandescent bulb. a) What is the total VA of the combined load? b) What is the overall PF of the combined load? c) What RMS voltage is the combined load operating?
