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
