Electric and electrical are essentially the same - they refer to any device that uses electricity. Flashlights are electric; we also have electric lights and electric heaters, and nowadays even electric cars. Something that is electric just uses electricity for energy.
Something that is electronic is a more complex system - it manipulates the electrical energy in ways that allow for more advanced functions, such as
transmitting information. Computers are electronic, and we also use electronic for digital versions of things in the physical world, like electronic stores/books.
