RE: [TCML] Primary selfC
Hi Paul,
Thank you for chiming in. This is something that is counter-intuitive and perplexes me too. Perhaps you can shed some needed light.
Intuition suggests that Cself is dependant on more than just the overall dimensions of a coil - that the capacitance between adjacent turns would factor prominently. Would a space-wound coil have the same Cself as a close-wound coil wound on the same form? Would a ribbon-wound coil (case in point) with air between the turns have the same Cself as the same coil with a high k dielectric between the turns?
No doubt the answer is yes to both, but it's not clear why.
Thanks in advance,
