Problem 23.60

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 0.3Ω resistor shown inside the battery. In this case, the brightness of bulb A changes when the switch is closed. Assume E=2.0 V.

Part A

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

Part B

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