Why “photoimpedance” is a great word
Photoimpedance is the complex opposition to alternating electrical current that varies with the intensity of illuminating light. Its construction is transparent: from photo- (from Greek phōs, phōt- 'light') + impedance (from Latin impedīre 'to entangle, hinder'), with "impedance" itself a twentieth-century coinage in electrical engineering. Unlike "photoresistance," which isolates only the resistive component, or the general term "impedance" which lacks the luminous condition, photoimpedance captures the full electrodynamic response. It is the phantom capacitance of a sun-warmed sensor, the inductive sigh of a shadow falling across a component, the subtle shift in phase as dawn touches a semiconductor. Here is the subtle truth: that even the abstract mathematics of alternating current must kneel to the physical presence of light.
