(a) When the ac generator in FIGURE 24-33 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 24-33

(b) Choose the best explanation from among the following:
I. The current is the same because at high frequency the inductor is like an open circuit, and at low frequency the capacitor is like an open circuit. In either case the resistance of the circuit is R.
II. Less current flows at high frequency because in that limit the inductor acts like an open circuit, allowing no current to flow.
III. More current flows at high frequency because in that limit the capacitor acts like an ideal wire of zero resistance.
