Data record qty.impedance.frequency-dependence

Verified 2026-10-27 Confidence: High

Because reactance depends on frequency, the impedance of a circuit that contains inductance or capacitance changes with the frequency of the applied voltage while its resistance, to a first approximation, does not; an impedance reading is therefore stated together with the test frequency at which it was taken.
