WebMar 29, 1999 · Inductance is a property of an electric circuit by which a changing magnetic field creates an electromotive force, or voltage, in that circuit or in a nearby circuit. Inductance is also defined as the property of … WebCalculating for Reactive, True, or Apparent Power As a rule, true power is a function of a circuit’s dissipative elements, usually resistances (R). Reactive power is a function of a … In electrical circuits, reactance is the opposition presented to alternating current by inductance and,or capacitance. Greater reactance gives smaller current for the same applied voltage. Reactance is similar to resistance in this respect, but does not lead to dissipation of electrical energy as heat; instead, energy is … See more Reactance is similar to resistance in that larger reactance leads to smaller currents for the same applied voltage. Further, a circuit made entirely of elements that have only reactance (and no resistance) can be treated the same … See more Inductive reactance is a property exhibited by an inductor, and inductive reactance exists based on the fact that an electric current produces a magnetic field around it.
