[ɪmˈpiːd(ə)ns]
noun
- the effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance
阻抗。 参见 acoustic impedance - Impedance is usually expressed as a complex quantity Z = R + jX, where R is resistance, X is reactance, and j is the imaginary square root of -1
阻抗一般以复量Z = R + jX 表示，其中R 为电阻，X 为电抗，j 为-1的虚数平方根
