What is a disadvantage of the series if more light bulbs were added
A.
If more light bulbs are added, resistance decreases, the current and the brightness of the light bulbs decrease.
B.
If more light bulbs are added, resistance decreases, the current and the brightness of the light bulbs increase.
C.
If more light bulbs are added, resistance increases which causes the current, and the brightness of the light bulbs to decrease.
D.
If more light bulbs are added, resistance increases which causes the current and the brightness of the light bulbs to increase.
