2 )Bulb A will be dimmer than bulb B.
3 )Bulbs A and B will be equally bright.
4 )Bulb A will be brighter than bulb C.
5 )Bulb A will be dimmer than bulb C.
6 )Bulbs A and C will be equally bright.
7 )Bulb B will be brighter than bulb C.
8 )Bulb B will be dimmer than bulb C.
9 )Bulbs B and C will be equally bright.

(b) With the circuit still turned on, what will happen to the brightness of each bulb when the switch is closed? Select all the correct statements from the list below.

1 )The brightness of bulb A will increase.
2 )The brightness of bulb A will decrease.
3 )The brightness of bulb A will remain the same.
4 )The brightness of bulb B will increase.
