If identical light bulbs are wired in parallel, how do they compare to one another in terms of brightness? How is this brightness affected if more bulbs are added to the
circuit?
a. identical bulbs in a parallel circuit will have the same brightness. Adding more bulbs will increase the brightness of all the bulbs.
b. Identical bulbs in a parallel circuit will have the same brightness. Adding more bulbs will decrease the brightness of all the bulbs.
C. Identical bulbs in a parallel circuit will have a different brightness depending on how far they are from the battery. Adding more bulbs will increase the
brightness of all the bulbs.
d. Identical bulbs in a parallel circuit will have a different brightness depending on how far they are from the battery. Adding more bulbs will decrease the
brightness of all the bulbs.
