Question 20 • Physical Science

How do the lights in a series circuit behave when one bulb burns out?

Answer
A
The rest of the bulbs continue to shine at a lower brightness.
B
The rest of the bulbs continue to shine at maximum brightness.
C
The rest of the bulbs continue to shine at a higher brightness.
D
The rest of the bulbs stop shining and shut off.

Explanation

In a series circuit, electricity has only one path through all the bulbs. When one bulb burns out, it breaks that path, so current stops flowing through the entire circuit. Therefore, the other bulbs stop shining and shut off.
