Transformers in Series, calculating the current

  1. Aug 15, 2006 #1
    I have been given the attached question by my mentor.

    I have used the standard transformer equations (Vs/Vp=Ns/Np etc.) but I am struggling to work toward the right answer. I am using 4 amps for question A (standard ohms law) but don't think I am tackling this right. As for current in the primary I always seem to come up with 1.6 amps. My mentor has told me this is wrong and I should be looking at the two unknowns. I'm completey stuck!!!

    Can anyone help?
