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 Ω resistor shown inside the battery. In this case, the brightness of bulb A changes when the switch is closed. Assume E = 1.9 V.

How much power does bulb A dissipate when the switch is closed?
