By what percent does the current through A change when the switch is closed? I just need Part C. I can't figure it out. Problem 28.54 For an ideal battery (r 02), closing the switch in (Figure 1) does not affect the brightness of bulb A. In practice, bulb A dims just a little when the switch closes. To see why, assume that the 1.50 V battery has an internal resistance 0.80 2 and that the resistance of a glowing...
