Elektronika je područje elektrotehnike . koja proučava i koristi sustave čiji se rad temelji na kontroli protoka elektrona i drugih nositelja električnog naboja. To su primjerice elektronički elementi kao: tranzistor, dioda, elektronska cijev i sl. Povezivanjem više elektronskih elemenata zajedno nastaju elektronički sklopovi. Centres.
