Electrical Reactance - Analysis

Analysis

In phasor analysis, reactance is used to compute amplitude and phase changes of sinusoidal alternating current going through the circuit element. It is denoted by the symbol .

Both reactance and resistance are components of impedance .

where
  • is the impedance, measured in ohms.
  • is the resistance, measured in ohms.
  • is the reactance, measured in ohms.

Both capacitive reactance and inductive reactance contribute to the total reactance .

where
  • is the capacitive reactance, measured in ohms
  • is the inductive reactance, measured in ohms

Capacitive reactance is non-positive and inductive reactance is non-negative.

Thusly,

  • If, the reactance is said to be inductive.
  • If, then the impedance is purely resistive.
  • If, the reactance is said to be capacitive.

Famous quotes containing the word analysis:

    “Ask anyone committed to Marxist analysis how many angels on the head of a pin, and you will be asked in return to never mind the angels, tell me who controls the production of pins.”
    —Joan Didion (b. 1934)

    “... the big courageous acts of life are those one never hears of and only suspects from having been through like experience. It takes real courage to do battle in the unspectacular task. We always listen for the applause of our co-workers. He is courageous who plods on, unlettered and unknown.... In the last analysis it is this courage, developing between man and his limitations, that brings success.”
    —Alice Foote MacDougall (1867–1945)

    “Cubism had been an analysis of the object and an attempt to put it before us in its totality; both as analysis and as synthesis, it was a criticism of appearance. Surrealism transmuted the object, and suddenly a canvas became an apparition: a new figuration, a real transfiguration.”
    —Octavio Paz (b. 1914)
