reaktáns

A reaktáns is a component in an electrical circuit that stores energy in an electric or magnetic field. Unlike resistors, which dissipate energy as heat, reaktant components do not consume power. The two primary types of reaktant components are capacitors and inductors. Capacitors store energy in an electric field, and their opposition to current flow is called capacitive reactance. Inductors store energy in a magnetic field, and their opposition to current flow is called inductive reactance. Both capacitive and inductive reactance are dependent on the frequency of the alternating current (AC) flowing through them. At low frequencies, capacitive reactance is high, while inductive reactance is low. At high frequencies, the opposite is true. The total opposition to current flow in a circuit containing both resistance and reactance is called impedance. Reactance is measured in ohms, the same unit used for resistance. Understanding reactance is crucial for analyzing and designing AC circuits, particularly in applications involving filters, oscillators, and power transmission.
