What is difference between electrical and electronics?

In Electrical, flow of electrons is through conductors/ metals. 

All the study, engineering and technology, devices, equipments, plants, tools, components, machines in which the flow of electrons (current) through conductors / metals is involved, are called electrical. 

Fans, Motors, refrigerators, Power generation, transformers, generators, heaters, power transmission, power distribution, and so many are some examples of electrical. 

In Electronics, flow of electrons are through semiconductors/ vacuum. 

All the study, engineering and technology, devices, equipments, plants, tools, components, machines in which the flow of electrons (current) through semiconductors/ vacuum is involved, are called electronics. 

Transistors, Diodes, Thyristors, Radios, TV, Picture tubes, vacuum tubes, computers, mobile phones, etc. are some example of electronics. 

(I wondered this. Electrical is generally large scale, domestic and commercial power, and appliances, whereas electronics is smaller scale, printed circuit boards and microprocessors).

Simply: 

ELECTRICAL means flow of electrons. 

ELECTRONICS means study of electrons.
