Trying to get 7 leds to light up on a 9V battery. Running them in parallel with resistors on each light. I'm a complete newb but was trying things out after reading a few articles. Clearly I am doing something wrong because the last two leds in the circuit don't light up.
The battery is emitting 9.49V so I know that's good. The 2 leds that don't turn on have been tested independently and work.
Led specs are 3V/20ma.
I used the R= (9V-3V)/0.02 = 300.
I used 330ohms resistors.
What am I doing wrong?
