Hi all... need help desperately...
I am wiring 108 x 3mm led bulb(white) in parallel.
Voltage drop of white led bulb should be appx 4 volts.
Desired led current should be appx 20mA.
I am currently using 4 x 1.5v AA batteries as source voltage
What kind of resistors should I get?
I used the resistor calculator and it showed me on "the wizard thinks 1/4W resistors/100ohms". Over at another website, it showed me "1/8 resistors/120ohms".
Please advice me on how much should I have for Supply/Source voltage and resistors.
Thanks a million in advance....
