Under the T-topology, the derivation of the “image” form of this quantity is necessary for analyzing constant k-filters. Matching two forms of this quantity is required for the extended form of Jacobi’s law. (15[1])The open-circuit test is used (15[1])to find the no-load form of this quantity (-5[1])in transformers. (-5[1])To solve transmission line problems, (15[2])a circular transformation (15[1])of the complex plane is mapped to a chart mainly for this quantity (-5[1])named (15[1])after Philip (15[1])(*) Smith. (10[1])This quantity for capacitors and inductors (10[1])is “one over (10[1])jwC” (10[2])and (10[1])“jwL,” (-5[1])respectively. (10[1])This quantity is often complex, (10[1])thus (10[2])it’s (10[1])represented as “R plus jX,” (-5[1])where X is the reactance. (10[1])Just like its DC counterpart, this quantity’s (10[1])units are in (-5[1])ohms. (10[3])For (10[1])10 points, (-5[1])name this quantity (-5[1])defined (-5[1])as the (10[1])alternating current form of resistance, (10[1])symbolized Z. ■END■ (10[3]0[3])
