I want to limit voltage (and current) to my load. Normally I use a voltage regulator (with 2 capacitors). But then I realized I can just use a resistor to drop the voltage (and subsequently, current). But then I thought, actually whats the difference between the two choices? Both drop voltage (and my load will draw less current because of it), and both solutions generate waste heat. Is there a difference? I'm still an electronics noob, so answers with a bit more detail would be greatly appreciated (because there's a greater chance I'll understand the answer that way).
Thanks!
Thanks!
