I am an electronics newbie. I am about 5 hours into the videos on this site which are very helpful.
I am building a golf ball display case that includes 27 LEDs. My initial design includes 27 white LEDs, 27 330 Ω resistors, and a 9v battery.
After watching one of the videos I learned about how to calculate the resistance properly for this type of circuit. Doing the math myself (which I hope is correct) it appears the total resistance for this circuit is 12.22 Ω. Does that mean I can put a 12.22 Ω resistor (or whatever standard resistor is closest) just off the power source and not include the 27 resistors I expected to use?
Thanks for your help.
