we know watts=voltage x amps.
I have 3v leds which runs at 300ma
so its watt = 3 x .3 = 0.9 watts
I have a 2 amps power supply with output 30vdc
so it can handle watts = 2 x 30 = 60 watts
there for i can run 60/0.9 = 66 leds
what i am confused about is if my power supply only provides with 2 amps then i can max run 2/0.3 = 6 leds
which above calculation is correct. I know i am missing something.
Thanks and Regards.
