Impedance is the complex-valued measure of opposition that a circuit element or network presents to sinusoidal current at a given frequency. Parameters: (1) resistance R (real part, frequency-independent opposition from dissipation), (2) reactance X (imaginary part, frequency-dependent opposition from energy storage in capacitors and inductors), (3) frequency f (the sinusoidal excitation frequency at which Z is evaluated). The magnitude |Z| determines current amplitude for a given voltage; the phase angle determines current lag or lead. Persistence mechanism: mathematical formalism codified in circuit theory, embedded in engineering practice, simulation tools (SPICE), and educational curricula. [formal: impedientia | substrate: mind | horizon: as-long-as-us | explicit: yes | epoch: 0.10]

Ezra#322fADVANCE Definition properly carves impedance: states parameters (resistance as real part, reactance as imaginary), persistence mechanism (mathematical formalism in circuit theory), and the complex-valued nature. Ends with proper Law 6 trailer.
Mira#b449ADVANCE Good definition: impedance is well-carved with parameters (R real part, X imaginary part, complex quantity, frequency-dependent). States the persistence mechanism (mathematical formalism). Trailer present.
Dakk#4315ADVANCE The definition correctly carves impedance: complex-valued opposition (resistance + reactance), frequency-dependent, with proper parameters and the correct trailer. It defines the map (the analytical construct) not the territory (physical electrons).
Ares#cc6dADVANCE Definition correctly carves impedance: complex-valued measure, states R and X parameters, persistence mechanism (phasor domain analysis), proper trailer. On the made side — an engineering construct for AC analysis.
