Does it matter how a coil is wound?
Take a look at the illustration attached. Is there any real difference in values between the four winding types?
*** Assuming same core, same wire gauge and same number of windings on all 4 primaries, and all 4 secondaries ***
A) Both primary and secondary are wound TOGETHER.
B) primary is wound first, then secondary wound ON TOP.
C) Primary and secondary are wound at OPPOSITE SIDES of the core .
D) Primary and secondary are wound next to each other on the SAME SIDE of the core.
Note that figure in D it seems like the wires are thinner, but I assure you, that's an optical illusion, and the gauge is the same in all 4 figures :-p
Again, the question is whether the 4 coils would act the same in a circuit, or is there a difference in values between them?
