On the Impedance Loci for Forced Damped Oscillations in Simple, Scries Circuits.

Abstract

The current and displacement impedance graphs as well as those of admittances of simple series circuits of two and three elements are shown when one component of the hyperbolic complex angular velocity -α+jω is varied. Straight lines, circles, parabolas, inverse parabolas, circular cubits and inverse circular cubics appear as such locus graphs. Angular velocities of natural decays or oscillations are also discussed on these graphs.
A correction of an oscillographic record of damped oscillation is explained as an application of such locus curves. And a transients in impressing to a L-R circuit an oscillating emf. gradually growing is also appended.
