Huh..."Al is irrelevant for transformers"<br /><br />Huh? Al allows you to calculate the inductance of a winding. Look at the basic transformer equations and you'll see there's a direct relationship between primary and secondary inductance, just as there is with the number of turns on a winding.<br /><br />Try the mini-Ring Core Calculator from DL5SWB:<br /><br />http://dl5swb.de/<br /><br />Look at the Help screens in mini-Ring, some good explanations there.Anonymousnoreply@blogger.com
