Q: electronic と electric と electrical はどう違いますか?
A: "electronic" means it's to do with electronics - that is, technology which is very complicated, usually computerised, and assembled from lots and lots of very small or even microscopic parts. A computer is electronic. A fridge or a washing machine is electrical, but (unless it has a computer on board) is not usually electronic.

"Electric" and "electrical" are much more similar, but in practice, there are far fewer cases when you would use electrical.

Q: electronic と electric と electrical はどう違いますか?
A: Electronic: more advanced devices like cell phones, televisions, digital watches, etc. If it has a circuit board, it's electronic.

Electric: simpler devices (usually tools) that use electricity, like an electric razor, toothbrush, guitar, oven or motor (and, by extension, even a car). Think 'something that has electricity passing through it.'

Electrical: something that pertains to electricity, but which doesn't necessarily utilize electricity itself. "Electrical tape" is a good example - it's non-conductive, so it's used to tape electrical wires (which themselves are not considered "electric" because they do not use the electricity, but merely carry it).
