Electronic means working by circuits and small components. Electronic equipment, an electronic device, electronic music.
Electronics is the field, and it is distinguished from electrical engineering by dealing with small signals and control rather than with power. Electronic music is made with synthesisers and computers rather than acoustic instruments. Note e- as a prefix — email, e-commerce, e-book — all of which are electronic shortened to one letter; and that electronic has been quietly dropping out of use as everything became electronic and the word stopped distinguishing anything.
