Hello, I have a quick question that maybe someone could answer here. I know that if you have a Bifilar coil with the winding in a way so that the current goes in the opposite directions then your Inductance of that coil is close to zero (I know it will never reach 0, Impossible ) Now the part I am not sure about has to do with the bifilar coil when wound in series con-fig (I think it is series ) Here is a picture: http://merlib.org/node/5516 it is the second one. Would the this configuration have a lower inductance then a standard coil. My reasoning for this is that since the coils are furthur apart, they would not be affected as much by the current flowing through the coils. If you follow the flow of the current then you see that it travels withing the coil then exits back out and then goes back into the coil through the second winding? So would the inductance be smaller or would it be the same as a standard coil or would it be bigger?
