Will the brightness be affected ?

Question

will the brightness be affected if there are two cells in a circuit but only 1 bulb

pls ans quick!!!!!

Answer 1

This depends on how the batteries are connected:

if paralel: it won't affect

if in series: it will

(conection in series means:  one's  '+ pole' is directly connected to other's  '- pole' only)

Answer 2

brightness depends on the battery voltage and on the ratings of the bulb.

I think you left off part of the question.
