resistors for leds why? Answered
i know i need resistors for leds, i know how to calculate what i need, etc. etc. but what im wondering about is why.
why arent leds like glowing bulbs, what makes the difference in needing the resistor.
also, why cant 1 resistor take care for multiple leds at the same time?
please, if ur answering my questions, make it understandable english. im not comfortable enough in the world of science to understand that kinda stuff... (otherwise i wouldnt be asking these questions :D )
