Newbie LED series resistor
Posted: Fri Sep 21, 2012 6:25 pm
Hi,
Newbie question - but I will remember the answers and gradually learn!
If I have created a potential divider to provide the power supply for a LED should I still put a resistor in series to control current, or does the aggregate resistance of the potential divider do the job anyway?
Thanks
