Impedance, however, does not equal the sum of resistance and reactance.Physics|Willis Eugene Tower
The impedance of the coil I is changed by moving its adjustable core.Cyclopedia of Telephony and Telegraphy, Vol. 2|Kempster Miller
Now one is apt to think in the first moment that the impedance of the wire might have something to do with the phenomenon.The inventions, researches and writings of Nikola Tesla|Thomas Commerford Martin
The impedance coils are wound on insulating rods, which hold them near, but not touching, the ground carbon.
The impedance of the clearing-out drop prevents the windings being shunted across the two sides of the cord circuit.
