For an ideal battery (r = 0 $2), 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 r = 0.60 2 and that the resistance of a glowing bulb is R= 4.00 2.
