A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up. When a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates. [pdf]
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 way as a circuit made entirely of resistances. These same techniques can also be used to. .
In electrical circuits, reactance is the opposition presented to by and . It's measured in . Along with resistance, it is one of two elements of ;. .
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. In the context of an AC. .
A capacitor consists of two separated by an , also known as a .Capacitive reactance is an opposition to the change of voltage across an element. Capacitive reactance $${\displaystyle X_{C}}$$ is .
Both reactance $${\displaystyle {X}}$$ and $${\displaystyle {R}}$$ are components of $${\displaystyle {\mathbf {Z} }}$$ [pdf]
