For a project I have 20 pieces of EL wire that each have their own 3V (2xAA) inverter. Now I think it's a complete waste and hassle to replace the batteries every so many hours, so I wanted to try and power the inverters from the mains.
What I am worried about with just connecting a 3V adapter is that with dropping the internal resistance of the batteries will result in a too high current that will fry the system (like with LEDs), will this be the case? Is there any way to control the current that will flow?
I have tried different resistances with a 6V power source, but I haven't been able to find one that still powers the circuit with 3V and creates a 70-125mA current (this is what I measured the circuit draws when powered by batteries), and I think I have fried one of the circuits so now I am afraid to do more experiments.
Note: an alternative is to get a 12V driver and a 12V adapter from the shop (I think). However, in this way I lose the different settings that come with the battery pack, which is undesired for my project.
Edit: I have tried to split the 6V into 3V according to the following diagram: The R1 and R2 are resistors and the yellow thing is my unknown EL wire circuit that I want to power. I used 220Ohm resistors for both R1 and R2 which results in a nice 3V over the circuit. However, the current over the circuit is not enough because of the resistors. Would it work with lower resistors?
