Consider a circuit consisting of a lightbulb and a capacitor .
Part A:If the frequency of the generator is increased, does the intensity of the lightbulb increase, decrease, or stay the same?
Part B:Choose the bestexplanation from among the following:
The intensity of the lightbulb is independent of frequency because the circuit contains a capacitor but not an inductor.
The intensity of the lightbulb increases because as the frequency becomes higher the capacitor acts more like a short circuit, allowing more current to flow.
As the frequency increases it becomes harder to force current through the capacitor, and therefore the intensity of the lightbulb decreases.
