Two electrical loads are in operation: Load 1 consumes 10 kW at 0.8 pf lagging and Load 2 has an apparent power of 25 kVA at 0.6 pf lagging. What is the total power factor of the combination of the loads in percent? A series circuit of two pure elements has the following applied voltages and resulting currents of 282.843 sin (314.159t + 30°) volts and 7.071 sin (314.159t - 23.13°) amperes respectively. What is the percent power factor of the circuit?
