阻抗（impedance）是电学领域描述电路或材料对交变电流阻碍作用的物理量，其测量单位为欧姆（Ω）。 该术语广泛应用于电路设计、天线系统分析及生物医学工程等领域，具体表现形式包括输入 …

Electrical impedance, measure of the total opposition that a circuit or a part of a circuit presents to electric current. Impedance includes both resistance and reactance.

Impedance is the measure of opposition to alternating current in electrical circuits, combining resistance, inductive reactance, and capacitive reactance.

Impedance is the total opposition a cable or circuit offers to alternating current (AC). It combines resistance and reactance, measured in ohms (Ω), and determines how readily AC signals pass …

May 13, 2024 · Impedance, often symbolized by Z, is a comprehensive term that describes how a circuit element restricts the flow of alternating current (AC). It’s a bit more complex than resistance, which …
