The current in a certain ac circuit is independent of the frequency at a given voltage. Which combination of elements is most likely to comprise the circuit?
A)resistors only
B)inductors only
C)capacitors only
D)a combination of inductors and resistors
E)a combination of inductors and capacitors

The fact that the current is independent of frequency suggests that the circuit has a purely resistive characteristic. This is because the impedance of an ideal resistor does not vary with frequency. Therefore, option A) is the most likely choice as it includes only resistors.
