When winding a coil around a magnetic core, if you wanted to tap the coil such that each half has the same AC voltage output, would you:(adsbygoogle = window.adsbygoogle || []).push({});

A) wind each part at the same RPM for the same amount of time, to get the same number of turns for each, or

B) wind the second part proportionally less, to compensate for the wider diameter of the coil as it grows

In A the DCR is greater in the second part, due to the longer length of wire needed to complete the wider turns.

In B DCR (and wire length) will be equal in both parts, but the second part will have fewer turns.

Thanks for your time!
