Electric vs Electrical vs Electronic
"Electric" and "electrical" mean exactly the same thing, and apply to anything that uses electricity, but mostly used for systems involving "passive" components &mdash; a battery or generator, motors, resistive loads, inductors and transformers, capacitors and maybe even rectifiers and relays.

"Electronic" is a term that is generally reserved for systems that incorporate "active" (electron) devices such as vacuum tubes or transistors &mdash; any device that can be said to have "gain", or the ability to proportionally control a large voltage or current using a small voltage or current.
