characteristic impedance

/ˌkarɪktəˌrɪstɪk ɪmˈpiːdns/

Physics

noun

A parameter of a uniform transmission line of indefinite length, equal to the ratio of the voltage to the amplitude of a single wave travelling along it; (equivalently) the impedance which when terminating an arbitrary length of line at its output will give rise to an input impedance of the same value; symbol Z₀.

For a lossless line the characteristic impedance is √(L/C) (where L and C are the inductance and capacitance of unit length of the line), and it is resistive..

Origin

Early 20th century. From characteristic + impedance.
