I want to know if the words electric, electrical, and electronic can be used interchangeably. They all seem to mean about the same thing... Any suggestions?
Answer
"Electric" and "electrical" mean exactly the same thing, and apply to anything that uses electricity, but mostly used for systems involving "passive" components — 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 — 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.
