1. A unity power factor of 1794 watts is connected in parallel with a load of 1656 watts operating at a lagging power factor of 0.6. if the line voltage is 115 V, calculate the current in each load, b) the total current c) the total power d) overall power factor e) the reactive volt ampere. 2. An additional load of 2108 watts is connected in parallel with Prob 1. If the overall power factor of ghe system is unity, calculate a0 the power factor of the added load b) the total current and power. 3. The following information is given in connection with three loads connected to a 220 V source: load A= 12 amp at unity power factor; load B is 40 amp at 0.5 lagging power factor; load C is 20 amp at a leading power factor of 0.9. Calculate the total current b) total power c) the reactive volt-ampere d) overall power factor. 4. Using the results obtained in Prob.3, calculate the equivalent impedance, resistance, and reactance of the system of the loads.
