Homework Help: Step-Up Transformer Conceptual Problem

  1. Apr 6, 2012 #1
    1. The problem statement, all variables and given/known data

    Even for an ideal transformer, we can't get "something for nothing". If this transformer steps up the voltage, what must be decreased?
    a) power
    b) current
    c) resistance
    3. The attempt at a solution


    I believe it's power or current, but these two are related. So i'm not sure which one to choose.

    An ideal transformer has no losses. What is your answer now?
