 * Well I thought my explanation in the module was pretty ok.But put what you have in mind here on this talk page and I'll be happy to discuss it with you. Theresa knott 21:39, 14 Nov 2004 (UTC)

Wrong Equation
Seems to me the equations Ip/Is= Np/Ns or, rearranging: Is= Ip * Ns/Np are wrong.

Actually, Vp/Vs=Np/Ns and since Vp*Ip=Vs*Is <==> Vp/Vs=Is/Ip, Is/Ip=Np/Ns.


 * You are absolutely correct. I mistakenly was thinking of the equation for voltage instead of current.  Sorry for the mess up. &mdash; Brim 14:40, 8 Dec 2004 (UTC)
