Imagine that you feed alternating current to an inductor with high inductance and very low resistance. Suppose we slowly increase the frequency of this alternating current while keeping the amplitude ?0 of the applied emf constant. How does the amplitude i0 of the alternating current flowing in the coil change (or does it)?
