How many more times do you have to wrap a ferrite rod to achieve the same power as a toroid bead? Answered
So recently I found a neat low-voltage fluorescent driver instructable, it calls for a large toroid as its inductor, I dont have any large toroids, but I do have a ferrite rod. What I want to know is if I have to wind 90 turns of wire on a toroid, how many do I have to wind on the rod? I know it has to be more because the rod looses EMF through its ends.
thanks in advance,
