And there are places to learn other than online. FInd a copy of The Op AMp Cookbook - perhaps even at your library. It starts with the basics and goes through many typical applications.

Incandescent bulbs make light by heating something so hot it glows or incandesces. The more power run through it the hotter it gets, so the brighter it gets.<p>LEDs do not work by heating something up until it glows. It works by having electrons cross energy levels. LEDs can vary as to the efficienc...
