hello everyone. I am a novice when it comes to this stuff but recently i decided to crack open a piece of my computer ( an led strip) apart because it did not work anymore. I cracked it open and found that it had 2 LEDs and 2 resistors on the pcb. Now this is SMD style... so i used a mag. glass and found out the Resistors were marked 151.... i googled and found out the 151 resistors is a 150 ohm resistor.... I am trying to understand how the circuit even works? from my undestanding it is in series... Here is a diagram of how the pcb is layed out.
Now. I am currently in hawaii, its 10pm and wifes sleeping so im doing some research... so i do not have access to the power source... But i have a feeling the power source is 12v.. I will confirm this when I get home on sunday. But when i recreate this circuit in Virtual Breadboard, or 123d circuits.... for some reason it does not work...
Also the LEDs have a forward voltage of 3.5, and a reverse of 5 and 30mA for the current with 100mA for the max current before damage.. sorry forgot what that was called... reverse current? forgive me...
So my question is how does this even work... the LED strip is from a reputable company... why do they do it this way.... are the 2 resistors like this overkill? underkill? or just set up to work forever....
The other question is, can i get away with turn this into a parallel circuit? and if i do. what kind of resistors would i need for this to work properly and for a long time...
Possible parallel circuit?
