Morphology
The phrase is partly compositional: a B1 learner who knows 'bridge' (something that connects) and 'circuit' (an electrical path) can infer it denotes a kind of circuit that bridges or connects branches. However, the precise technical sense (the specific diamond/bridge arrangement used for accurate measurement, e.g. a Wheatstone bridge) is specialised knowledge beyond ordinary word meanings, so the full meaning is not predictable from the parts alone.
Etymology
The noun bridge circuit comes from the image of a bridge joining two paths of wire: the circuit makes two sides and a meter sits across the middle like a plank between them. Because the meter uses that bridge to 'compare' the two sides, the name means a circuit used to 'measure' electrical values.
