impedances in English

noun
1
the effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.
The constant impedance is maintained despite changes in temperature and voltage by using two external resistors to hold the impedances for all the I / O pins, which can number hundreds in the larger parts.
