LED Light Circuit
Hi, I know this is a specialized post but was wondering if someone here could answer. It's pretty basic.
I want to make a DC (battery) powered circuit of 2 LEDs in parallel. The space for the battery is very limited. So I was thinking about using a 9v battery (a 1.5v won't last as long). But the LEDs I could find are usually around 1.x volts. So I know I have to use appropriate resistors before each LED. I was wondering if the difference between the battery and the LEDs is large, would this be advisable? Like if the 2 LEDs were 3v combined and the battery was 9v. Would the 6v difference that the resistors had to reduce voltage by drain the battery more than if I could find LEDs that combined were closer to the 9v battery? I don't know much about how this works. Thanks!
