True or false: about Transformers

  1. Jun 10, 2011 #1
    1. when an alternating voltage is applied across the primary coil, an emf is induced in the secondary coil
    2. when an alternating voltage is applied across the primary coil, an alternating current is induced in the secondary coil


    can anyone tell me which one is true and why?

    Thanks a lot.

    What do you think? What equations do you know that are relevant? What concepts are relevant?
