Light Bulbs in a Parallel Circuit

What happens when you have three light bulbs wired in a parallel circuit and you remove one light bulb?

A. The other light bulbs will become dimmer.

B. The other light bulbs will remain at the same brightness.

C. The other light bulbs will become brighter.

D. The other light bulbs will go out.

Answer:

With one bulb removed, the other light bulbs will become brighter because they receive a higher current.

In a parallel circuit, each component (light bulb) is connected to the same voltage source independently.

When you remove or unscrew one light bulb in a parallel circuit, the other light bulbs will continue to receive the same voltage as before. With one bulb removed, the total resistance in the circuit decreases, resulting in an increase in the current flowing through the remaining bulbs.

As a result, the other light bulbs will become brighter because they receive a higher current.
