I've just bought 5 meters long 12V analog RGB LED strip and I'd like to turn it on! There're 60 LEDs per meter so, totally 300 LEDs and each LED consumes 20mA.
Here're my questions.
From internet guide like this(https://learn.adafruit.com/rgb-led-strips/usage), power is directly connected to white line then where is ground? (single LED have 4 legs - Red, Green, Blue and Ground, isn't it?)
If I have 12V DC Adapter and it throws more than 6A current, can I use it without resistors?
If the adapter throws more than 6A current, what happen to remained current? just gone away to somewhere?
Can I use higher voltage adapter if I use proper resisters?
thanks in advance and sorry for my bad English! :(
