Hello all.
I have a very basic question, halfway through my 1st year doing electronics and i'v asked my lecturer but i forgot his answer and i don't go back to wednesday.
Ok, simple circuit powering an led say. Generally you would put in the required value resistor before the led. However, in a few internet circuits i'v came across, the resistor is AFTER the led.
I'm assuming this is still limiting current but i don't get/can't remember how this is so.
So basically, can someone answer why a resistor would come after an led.
Cheers.
