Electrical Circuits

The picture shows an electrical circuit. This circuit is a series circuit because:

• It has 3 light bulbs.

• The same current flows through all three light bulbs.

• It uses a single battery.

• The electrical current is divided between the three light bulbs.

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.

• The other bulbs will stay on

• The other bulbs will get dimmer.

• The battery will become stronger.
