Usage examples
  • 150 mm stripline testing The test method allows the generation of homogeneous fields between an active conductor (the stripline 50 ` impedance), and a ground plane (the conducting surface of the mounting table), between which part of the wiring harness may be inserted.
  • An illuminating device in the position of use shall remain in that position if the malfunction referred to in 3.15.2.1 occurs alone or in conjunction with one of the malfunctions described in 3.15.2.2: 3.15.2.1. the absence of power for manipulating the lamp: 3.15.2.2. a break, impedance, or short-circuit to earth in the electrical circuit, defects in the hydraulic or pneumatic leads, Bowden cables, solenoids or other components controlling or transmitting the energy intended to activate the concealment device.

hõõrdetakistus
Usage examples
  • Maksumusliku kauguse (cost distance) arvutamisel ei mõõdeta vahemaad meetrites, vaid akumuleerunud kulus (nt aeg, kütus, raha või energiakulu), kus läbitud vahemaa korrutatakse sellel teelõigul valitseva hõõrdetakistusega.

impedance
Usage examples
  • This measure would be [...] in the form of a "friction factor" or an "index of impedance." In more general terms, it would be a measure of how many incremental units of travel cost (in this case, units of time) will be accumulated over a given physical distance.

  • elektriahelas vahelduvvoolule avalduv kogutakistus, mis on aktiiv- ja reaktiivtakistuse vektorsumma
  • measure of the opposition that a circuit presents to a current when a voltage is applied
  • opposition to alternating current presented by the combined effect of resistance and reactance in a circuit
näivtakistus preferred
Usage examples
  • Näivtakistus on kasutusel elektrivõrkude vahelduvvoolu analüüsi tegemiseks, sest see võimaldab seostada sinusoidseid pingeid ja voole lineaarselt.
