Question
If the battery in (Figure 1) were ideal, lightbulb A would not dim
when the switch is closed. However, real batteries have a small
internal resistance, which we can model as the 0.3 2 resistor
shown inside the battery. In this case, the brightness of bulb A
changes when the switch is closed. Assume & = 2.5 V.
