C. The switch is now opened. Does the brightness of bulb A increase, decrease, or remain the same? O The brightness of bulb A increases. O The brightness of bulb A decreases. C) The brightness of bulb A remains the same. \fDoes the brightness of bulb D increase, decrease, or remain the same when the switch is Opened? 0 The brightness of bulb D increases. 0 The brightness of bulb D decreases. O The brightness of bulb D remains the same. The circuit is repeated at right for your convenience. The switch is still closed. Compare the potential difference across bulb B to that across bulb C. B D O The potential difference across bulb B is A C greater than the potential difference across bulb C. The potential difference across bulb B is less than the potential difference across bulb C. The potential difference across bulb B is equal to the potential difference across bulb C
