Alternating Current

Analysis of LCR circuits, resonance, and the operation of power transformers.

Key Questions

  1. 1Why is alternating current preferred over direct current for long-distance power distribution?
  2. 2How does the phase relationship between voltage and current change in reactive components?
  3. 3What determines the 'Q factor' of a resonant circuit and why does it matter in radio tuning?
