I have 3x 3v White LEDs that are to be powered with a 3v battery (3x CR2032 in series).
The forward voltage of the LED is 3.0v-3.2v. From my understanding, you always want to use a resistor in the circuit. SO with this setup the LED would be slightly dimmer.. but what ohm resistor do I need to use?
