Hey guys! I know this is probably a very basic EE question, but I can't seem to find the answer after searching for several days. Also, this is my very first EE project ever so I'm trying to absorb everything as quick as I can, but there's something I can't wrap my head around.
So, when calculating resistors, you need to know three things. Voltage from your source (6v in this case), forward voltage, and amperage. That much I understand. I've got two LED's to power: the main saber, and an accent LED. So after some research, a parallel circuit seems the way to go.
My question is this: When calculating a resistor for each of the LED's (since they're each on their own parallel circuit) do you have to take into account the draw of the previous LED, or can you calculate the resistor of each LED in a vacuum, assuming that the battery pack supplies 6V to both 'paths' of the parallel circuit? From what I read, that seems to be right, but I wanted to confirm.
Does that make sense? I can draw a diagram if need be.
Thanks so much for your help!
