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:
“... 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)
“The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
—Henry Brooks Adams (1838–1918)
