Three identical resistors are connected to a lightbulb as shown in the figure. Assume the battery and all wires are ideal. Initially the switch is closed and the bulb is on. What happens to the brightness of the bulb if the switch is opened? ーーー The bulb briefly gets dimmer but then returns to its initial brightness. The bulb gets brighter. The bulb's brightness is unchanged. The bulb gets dimmer. The bulb briefly gets brighter but then returns to its...

For an ideal battery , closing the switch in the figure
(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 1.5 V battery has an internal resistance and that the resistance of a glowing bulb is

3. For an ideal battery (r- 02), closing the switch in the following figure does not affect the brightness of bulb A. In reality, when a real battery with an non zero internal resistance is used, bulb A dims just a little when the switch closes. To see why, assume that the 1.5V battery has an internal resistance r = 0.5 Ω and that the resistance of a glowing bulb is R- 6S 1.5v÷ : lamp A amp B (a)...

For an ideal battery (r = 0 Ω), 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 = 0.90 Ω and that the resistance of a glowing bulb is
R = 8.00 Ω.
