Morphology

electrical + discharge

The phrase is fully compositional: 'electrical' specifies the domain (electricity) while 'discharge' denotes a release or movement, so together they directly denote a release/passage of electricity. This adjective + noun combination is a straightforward, cross-linguistic pattern and would be inferable by a B1 learner who knows the constituent words.

Etymology

Electrical discharge gives a simple picture: electrical means electricity and discharge means a sudden 'release' or 'jump' of that electricity, like a bright 'spark' or lightning. So it means the sudden passing or 'flow' of electricity that you can sometimes see as a flash.
