One of the most fundamental concepts in our profession is impedance. Due to the nuances of the mathematics related to this quantity, the minutia of what is taking place and the associated nomenclature ...

The theory developed in II is extended to cover the case of a superconductor, and a formula is derived relating the r.f. resistivity to the superconducting penetration depth and other parameters of ...

Resistance and reactance collected by bioelectrical impedance (BIA) can be used in equations to estimate percent body fat at relatively low cost and subject burden. To our knowledge, no such equations ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

When shopping for loudspeakers or headphones, most consumers don’t even look at the impedance of the products they are considering. Do they need to? What is Impedance? Glad you asked. Most consumers ...

Providing all the well-known measurement parameters: Impedance |Z|, Admittance |Y|, Phase Angle(?), Reactance(X), Conductance(G), Susceptance(B), Inductance(L ...
