So I'm hoping someone can help me understand my problem here! (Also sorry if this question has been asked before !)
I've done a simple led circuit before , a switch battery pack connected to led with no resistor and it worked fine considering it was powered by two AA batteries.
I'm making a prop weapon (I do costumes and props) and it needs three "glowing gems" so I casted resin and inserted white led lights into them. I need all three lights to be able to turn on and off with a switch while being on different sides of the weapon.
I currently wired the lights (extra ones ) to test and I can't seems to be able to power the second led light when wired this certain way. Positive wire of battery (two AAs) to positive of led. Negative pole of (first)led to positive of next led. negative pole to switch. Other side of switch to negative side of battery. When taking the second led light off everything seems to work fine but when adding the second light it stops working.
Would I be able to power the 3 white led lights with a 3volts battery pack ( 2 AA batteries ) or would I have to connect it to a 9 volt battery ?
Any help would be greatly appreciated!
