Question

difference between electrical and electronics

Answer 1

The link between electronic and electrical circuits is typically provided by relays or transistors. These are essentially switches but, rather than being pushed manually like a light switch, are operated by a small current from an electronic circuit.

Answer 2

Electrical is all about Generation (V), Transmission (I), Utilization (R), Measurement (V=IR & P=VI) and Manual Control (Switch /Regulator).
Electronics is all about Automatic Control (y = f(x)).  To implement the automatic control, in the initial days Vacuum Tubes were used, then Transistors were used. Now a days ICs are used in Electronics
