CE Predict/Explain Suppose the circuits shown in Figures 24–29 and 24–31 are connected to identical batteries, rather than to ac generators. (a) Assuming the value of R is the same in the two circuits, is the current in Figure 24–29 greater than, less than, or the same as the current in Figure 24–31? (b) Choose the best explanation from among the following:
The circuits have the same current because the capacitor acts like an open circuit and the inductor acts like a short circuit.The current in Figure 24–29 is larger because it has more circuit elements, each of which can carry current.The current in Figure 24–31 is larger because it has fewer circuit elements, meaning less resistance to current flow.

ANSWER:
Step 1 of 3
Suppose the circuits shown in the figures at the right are connected to identical batteries, rather than to ac generators. Assume the value of is the same in the two circuits.
We can use the characteristics of inductors and capacitors at low frequency to answer the question.
