FIGURE 24-1 Figure 24-1 shows a simple ac circuit composed of a capacitor connected across the terminals of an ac generator. If the frequency of the generator is doubled, what happens to the capacitive reactance of the capacitor? It increases by a factor of 2. It decreases by a factor of 4. It increases by a factor of 4. It decreases by a factor of 2. It increases by a factor of ?2.

Step 1
Step 1: The capacitive reactance of a capacitor in an AC circuit is given by the formula \(X_C = \frac{1}{2\pi f C}\), where \(f\) is the frequency of the AC generator and \(C\) is the capacitance of the capacitor. Show more…

A capacitor (capacitance C1) is connected across the terminals of an AC generator. Without changing the voltage or frequency of the generator, a second capacitor (capacitance C2) is added in series with the first one. As a result, the current delivered by the generator decreases by a factor of three. Suppose that the second capacitor had been added in parallel with the first one, instead of in series. By what factor would the current delivered by the generator have increased?
