Calculate LED voltage drop
hello all,
i have simple question studying myself count not find way calculate it.
to use led 9volt battery calculated needed resistor of 350 omhs, have 1k omhs resistor , when put them on circuit leds light poor (as expected).
simulating everycircuit showed power dropped 1.89v after 1k resistor.
how find 1.89v ?
thanks !

that informations on datasheet of led. must find graph or table must given current voltage drop of led x.
