True or false: about Transformers

  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.
