a 90 percent lagging power factor. Load B has an apparent power of 15 kVA with an 80 percent lagging power factor. Find the power, re- active power, and apparent power delivered by the source. What is the power factor seen by the source?

A load has a leading power factor. a) Is it a capacitive or inductive load? b) Is the reactive power positive or negative?  c) Repeat for a load with lagging power factor

Sine wave A has a positive-going zero crossing at 40°. Sine wave B has a positive-going zero crossing at 45°. Determine the phase angle between the two signals. What signal leads ? A Y-connected system can have wires. The (resultant) voltage between the hot legs (135V) is The phase angle between the phase voltage and the line voltage of a A-connected generator is degrees. The phase current produced by a certain 20V, Y-connected generator is 12A. The corresponding line current is A certain A-connected generator produces phase voltages of 30V. The magnitude of the line voltages are When the turns ratio of a transformer is 20 and the primary ac voltage is 6V, the secondary voltage is If 20W of power are applied to the primary of an ideal transformer with a turns ratio of 8, the power delivered to the secondary load is The turns required to match a 500 source to a 1000 load is
