What is the main difference between electrical and electronics?

We know that the term electronics has its origin from the invention of the diode and triode valves from electricity. Therefore we can define electronics in terms of electronics as a branch of electrical that studies about an active electrical device with a passive device which is known as electronics.

Some used to say - the study of high voltage AC and AC devices is called electrical while the study of low voltage DC and DC devices is called electronics.

This is partly true, but not absolute because in power electronics we control high voltage AC power using active electronic devices such as SCR, Triac, etc., so the branch is called power electronics and not electrical.

If you glow an ordinary 3v filament bulb, it is not part of the electronics, while it is part of the electromagnet, using battery DC.

Electrical also studies the magnetic and heating effects of electricity. Electronics may also include magnetic and thermal measurements but active devices must include this.

Controlling the light intensity of the 3v filament bulb using a rheostat comes in electrons while controlling the light intensity of the 3v filament bulb using transistors and presets comes into the electronics.

Some people used to say - electrical equipment manages the flow of electricity and electronic example manages the flow of information. This is true whether they work with AC or DC.

For example, we can say that a DC supply, such as a cell, is an electrical device because it is designed to manage the flow of power. Remember that television is an electronic device because its electronic circuits manage the flow of information in the form of sounds and pictures.
