Question

1. what would happen to the lights in the circuit if one of the light bulbs was unscrewed?

image of a series circuit with three light bulbs, a battery, and a switch
options:

• the remaining light bulbs would get brighter
• the remaining light bulbs would get dimmer
• they would remain the same
• all of the bulbs would go out

Explanation:

The circuit shown is a series circuit (components connected in a single path). In a series circuit, if one component (like a light bulb) is removed (unscrewed), the circuit becomes open, and current stops flowing. So all bulbs will go out.

Answer:

D. All of the bulbs would go out
