Hi
I'm a little rusty on my transposition of formulas.
vp/vs = np/ns is the gerneral formula for transformers. I rewritten it in order to get vs on it's own. Hence it be Np/ NsX Vp. However the answer I get doesn't match the one on the answer sheet until I flip it upside down to get Ns X Vp / Np. Why do I need to flip it upside down? I seem to vaguely remember this from school.
