What is the difference between electronic device and electric device plz help me urgent?

I believe that the classification is arbitrary but would be based on the type of components. Electric motors, heaters and light bulbs are electric devices. An integrated circuit is a electronic device.

electronic generally refers to things with ACTIVE components-transistors of some sort. Electric generally refers to INACTIVE devices-R L C components only. Some contain both, then it'sa question of whether the ACTIVE components are the primary ones, even if essential to operation. There are 'industry traditions' involved.

The transistor and integrated circuit, mainly. The world's first computers used normal electric power and vacuum tubes to regulate voltage. The invention of the transistor allowed a voltage relay to be contained within a solid-state circuit. And integrated circuits on silicon allowed very complex systems of transistors. So for a minute amount of voltage you can design a system where one circuit will be relayed exactly 1 of those units, the next one two, the next one 4, the next one 8, and so on up to 128, which means that every time you send a voltage from 0 to 255 across the relay, it will be directed to a unique set of those circuits that correspond to the binary representation of the 0 to 255 number. That's how computers work, and electronic devices use the same principle fundamentally, though it's not all bits and bytes of data, it's based on integrated transistors.

That depends on the context. Essentially they can both represent the same thing.
