Hey guys, I'm very new to electronics so any help would be much appreciated.
I've got a several big LEDs that I want to light up. Here is what their ratings are: 2.4V/20mA
I'm going to use an old computer's power supply to get steady 12v DC power from a wall outlet. It's got 12v+ and 12v- pins and that can power up to 200watts so about 16amp capacity.
If I wire 5 of those LEDs in a series, (2.4 x 5) = 12v. Do I not need any resistor? Doesn't the current need to be regulated? That's the part I don't understand.
Thank you!
