Hi first off please be easy ive just started learning:
Why is this have a series circuit powered by 9v cell connected to 1x 150 ohm resistor and 3 leds in that order.
I want the forward voltages to be around 2 v across each led(safe Vf limit) but atm they are 6v,4v,2v.The currents(20ma) fine its just the Vf. The point is how do you design a series cricuit like this and not exceed the Vf safe limit for the first two leds?
