i m thinking of doing a circuit with ten white leds which are connected in series...i hav searched for the circuit diagram but i dint find...could any1 please give me a circuit diagram which u hav tried and u are getting the output....
To have ten white leds burning you must have a powersupply.
What voltage does your powersupply have?
What type of white leds are you going to use (datasheet)?
LEDs vary in voltage, even within the same family. Figure white LEDs are a max of 3.8V Vf each, that means you would needs 38V at least to power them, and more voltage would actually be necessary.
You would be better to have 5 in series with 2 legs, with would still work to a minimum power supply voltage of 19V.
