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)
“Analysis as an instrument of enlightenment and civilization is good, in so far as it shatters absurd convictions, acts as a solvent upon natural prejudices, and undermines authority; good, in other words, in that it sets free, refines, humanizes, makes slaves ripe for freedom. But it is bad, very bad, in so far as it stands in the way of action, cannot shape the vital forces, maims life at its roots. Analysis can be a very unappetizing affair, as much so as death.”
—Thomas Mann (1875–1955)
“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)
