    Martin's Dynamo Circuit #7 - cap & tail-light query...

    Thanks again. Looks like i learn fast but have a limit to how much i can learn. This is how i brained out my circuit from what i think i understand so far: 1. Source voltage is what comes out of the dynamo and equal to all branches of a parallel circuit, around 6v. 2. Formula for resistors in...

    No. Im gonna test everything once i get my dynamo. I posted a picture of parallel leds, someone suggested leds in series and the thread derailed.

    Thats what i did but with different values (6V-2V)/0,02A=200ohms. Where did the rest of V go in a parallel circuit?

    Anyone? Tried posting on bikeforums and other forums, can´t get an answer from anyone that knows what they are talking about.

    Will this circuit work? White led headlight and a red led taillight on a current divider: rectified 6V 3W hub dynamo 4700uF capacitor in parallel with 10ohm resistor and a 480mA white led in parallel with 240ohm resistor and a 20mA red led cant post an image:(

    Complete dynamo LED circuit

    Thank you, that helped me understand. Looks like i was on the right track.

    Complete dynamo LED circuit

    Posting some relevant questons. 1. What if i want to run a bright headlight and a dim taillight from a hub dynamo? How do i split the current 80/20? With resistors? Or will that be like 50/20 + 30 wasted in a resistor? 2. I am confused about the voltage and current of dynamos and LEDs. If...
