Morphology

resonant + circuit

The phrase is compositionally a 'circuit' that is 'resonant' — a learner who knows both words can infer it is a circuit that exhibits resonance. However, the precise technical sense involving inductance, capacitance and frequency‑specific oscillations is specialized domain knowledge not predictable from general B1 vocabulary, so the expression is only partially transparent.

Etymology

Resonant circuit comes from resonant, meaning to 'ring' or 'vibrate' like a bell, and circuit, a path for electricity. In a resonant circuit the parts make the electric signal 'ring' strongly at one frequency, so the circuit can pick out or tune to that frequency.
