Morphology
The noun phrase is a straightforward adjectival composition: 'ohmic' (pertaining to Ohm's law) modifies 'resistance', so the meaning is simply resistance that obeys Ohm's law. Although technical, this sense is fully predictable from the constituent meanings and follows a common adjective + noun pattern familiar across languages, so a learner who knows both words will understand it.
Etymology
Ohmic resistance comes from the scientist Georg Ohm, and ohmic says the material follows 'Ohm's law' while resistance is how much it slows electric current. Imagine a narrow pipe that slows water: the more it narrows, the more 'resistance' and the less flow, so ohmic resistance is the amount a material slows current and is measured in ohms.
