electronics was developed in 1896 when the vaccume tube was invented.that vaccume tube was used as amplifier and it was working on the passage of electrons through gas or vaccume. this tube had three electrodes (anod cathode and the control grid).so from here,the inventer(which was electrical engineer)named this new field as ELECTRONICS.later on in 1947 the solid state devices (diode and transisters were made,which were made of semi-conductors.
SO ELECTRONICS IS THE STUDY OF PASSAGE OF CHARGES THROUGH GAS OR VACCUMME OR SEMI-CONDUCTORS.WHILE
ELECTRICAL IS THE PASSAGE OF CHARGES THROUGH CONDUCTORS...
