8AC Circuits Relationships

OBJECTIVES: After studying this chapter, you will be able to

  • Find current and power in almost all AC circuits
  • Use vectors for representing voltage, current, and their relationships in AC electricity
  • Describe differences between DC and AC circuits
  • Explain three types of power in AC and the relationship between them
  • Find the equivalent of inductors and capacitors in series and in parallel with each other
  • Describe phase difference
  • Define reactance, and understand inductive and capacitive reactance and how to measure them
  • Explain when inductors and capacitors are put in an AC circuit, what happens, and why there will be phase difference between current and voltage
  • Solve problems involving resistors, inductors, and capacitors ...
