Morphology
The meaning is compositionally built from 'direct' (one-directional) + 'current' (a flow of charge), so 'an electric current that flows in one direction' is directly derivable from the constituents. This adjective+noun pattern is regular and cross-linguistically common, so a B1 learner who knows both words should be able to infer the MWE's meaning.
Etymology
Direct current gets its name from the picture of current as a steady flow and direct meaning straight. Because it 'flows in one direction', like water moving down a single pipe, the phrase describes electric flow that does not go back and forth.
