Questions and Answers

In phasor representation, what does the phase difference between two waveforms indicate?

  • The time delay between the peaks of the waveforms. (correct)
  • The energy loss during waveform transmission.
  • The frequency at which the waveforms oscillate.
  • The amplitude of the waveforms relative to each other.

    • What is a primary advantage of using an AC system over a DC system in power distribution?

  • AC systems are more efficient for short distances.
  • AC generators are less costly to produce than DC generators.
  • AC can be easily converted to different voltage levels. (correct)
  • AC requires fewer components than DC systems for transmission.

    • Which term describes two waveforms that reach their maximum values simultaneously?

  • In phase (correct)
  • Out of phase
  • Lagging
