phasor

Examples of phasor in the following topics:

• Phasors

  • Phasors separate the dependencies on A, ω, and θ into three independent factors.
  • The term phasor therefore often refers to just those two factors.
  • There are two key ideas behind the phasor representation of a signal:
  • An example of series RLC circuit and respective phasor diagram for a specific ω.
  • Electrical engineers, electronics engineers, electronic engineering technicians and aircraft engineers all use phasor diagrams to visualize complex constants and variables (phasors).

• Capacitors in AC Circuits: Capacitive Reactance and Phasor Diagrams

  • Due to the phase difference, it is useful to introduce phasors to describe these circuits.
  • To get there, we will first introduce a very general, pictorial way of representing a sinusoidal wave, using phasor.
  • Phasors separate the dependencies on A (amplitude), $\nu$ (frequency), and θ (phase) into three independent factors.
  • In those situations, phasors allow this common feature to be factored out, leaving just the A and θ features.
  • A phasor can be seen as a vector rotating about the origin in a complex plane.

• Inductors in AC Circuits: Inductive Reactive and Phasor Diagrams

  • Therefore, the phasor representing the current and voltage would be given as in .
  • Again, the phasors are vectors rotating in counter-clockwise direction at a frequency $\nu$ (you can see that the voltage leads the current).
  • Subsequent Atoms will discuss how these phasors can be used to analyze RC, RL, LC, and RLC circuits.
