Morphology
Both constituents contribute directly: 'corona' (a faint luminous ionized-air glow) combined with 'discharge' (release or movement of electric charge) yields the literal compound meaning of an electrical discharge around a conductor. This is a straightforward noun+noun composition used in technical registers and follows transparent, cross-linguistic compounding patterns, so a B1 learner who knows both words can derive the MWE's meaning.
Etymology
Corona discharge comes from the word 'corona', meaning 'crown', because the effect looks like a small glowing crown or halo around a high-voltage wire. So, corona, meaning 'crown', and discharge, meaning 'a release of electricity', together name that faint electric glow.
