Hey guys i have what may be a stupid question again heh
Resisters are current limiters of course i know that but lets say your using any PIC that supplies a output pin with 5v @ 25mA.....
If i place a 200 ohm resistor to that pin and a led.... whill the led get 25mA still or will it drop.
The main question is.... As a current limiter... does the resistor 200 ohm resister just let the current pass through it as if it wasnt there since in ohms law 5v / .025mA = 200 ohms....
or will it drop the current further down?
Would a resistor even be usefull? or is it there for a current spike or something?
