Impedance vs admittance.

In order to express and quantify the effects of mixed resistive and reactive components, we had to have a new term: impedance, measured in ohms and symbolized by the letter “Z”. What is Admittance? To be consistent, we need a complementary measure representing the reciprocal of impedance.

The imaginary part is called "Reactance", and L and C are called "reactive elements". Reactance is the ratio of V/I, so it has the units of Ohms, just like resistance. The impedance of an inductor is Z = jwL.Names Illustration of the transform in its T-Π representation. The Y-Δ transform is known by a variety of other names, mostly based upon the two shapes involved, listed in either order. The Y, spelled out as wye, can also be called T or star; the Δ, spelled out as delta, can also be called triangle, Π (spelled out as pi), or mesh.Thus, common names for the transformation include …
