A measure of the opposition to the flow of an alternating current in a circuit; the aggregation of its resistance, inductive and capacitivereactance. Represented by the symbol Z. (noun)
Examples of word impedance
The term impedance is most often encountered in dealing with antennas and speakers in television, stereo, and radio systems.
Yes, the difference in impedance would be fairly large.
One of the problems the middle ear has to overcome is the mismatch in impedance between air and the cochlea, but impedance matching by the middle ear results in only a 30 dB increase in sound energy transmitted to the inner ear.
Guts: One of the problems the middle ear has to overcome is the mismatch in impedance between air and the cochlea, but impedance matching by the middle ear results in only a 30 dB increase in sound energy transmitted to the inner ear.
The phrase impedance matching seems to have moved towards mainstream language in recent times:
When effective resistances and reactances are connected together, either in series or parallel or series-parallel, then the equivalent resistance of the overall circuit is called impedance Z.
The issue with the Thiels is they have low sensitivity (84dB, I believe for the 3.6) and impedance, which is rated at 4 ohm but may actually be as low as 3.
The music reference hit home as well, as I often experienced this kind of impedance mismatch with the drummer from my old band - he's an inexhaustible fountain of music minutiae.
Furthermore expertise in a number of relative applied techniques, such as impedance spectroscopy will also be vital.
