(a) Which light bulb in Example 31.2 has the greater resistance?

(b) Suppose you connect each bulb separately to the battery. Do you expect the current in bulb A to be greater than, equal to, or smaller than that in bulb B?

Data from Example 31.2

In Figure 31.8, two light bulbs are connected to each other by a wire and the combination is connected to a battery. In steady state, bulb A glows brightly and bulb B glows dimly. If the magnitude of the potential difference across the battery terminals is \(9 \mathrm{~V}\), what can you say about the magnitude of the potential difference across \(\mathrm{A}\) ?
