Electronic Principles
Doubling the operating frequency of a purely inductive circuit:

doubles the amount of current through the inductors
has no effect on the current through the inductors
cuts the current through the inductors one-half
increases the current, but by an amount that can be determined only by doing a complete analysis of the circuit
None of these
