Question 2 (2 points)
The diagram below shows a simple electrical circuit:
terminals
Battery
C
B
switch
Which of the following things would increase the brightness of the lightbulb
a
Decreasing the number of light bulbs
Ob
Decreasing the battery voltage
Ос
Increasing the number of light bulbs
Od
Increasing the distance between bulbs A and B
b) Decreasing the battery voltage: Lowering the battery voltage would decrease the power supplied to the bulbs, leading to lower brightness. Therefore, decreasing the battery voltage would not increase the brightness.
