(a) When the ac generator in FIGURE 24-34 operates at high frequency, is the rms current in the circuit greater than, less than, or the same as when the generator operates at low frequency?
In figure 24-34

(b) Choose the best explanation from among the following:
I. The current at high frequency is greater because the higher the frequency the more charge that flows through a circuit.
II. Less current flows at high frequency because in that limit the inductor is like an open circuit and current has only one path to flow through.
III. The inductor has zero resistance, and therefore the resistance of the circuit is the same at all frequencies. As a result the current is the same at all frequencies.
