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.

• Circuit

• Insulator

• Resistance

• Conductor

This circuit has more than one loop. When one light goes out, the others stay on. 

• closed circuit
• series circuit
• parallel circuit
• open circuit

A series circuit has ____ path(s) that the electric current can take.

• One

• Two

• Three

• Four

This is an example of a _______ circuit

• open

• series

• parallel

• switch

Pick the correct sentence.

• This circuit will work because it is a closed circuit.
• Energy will freely flow in this circuit.
• This circuit will not work because there is no energy source.
• This circuit will not work because there is no switch.

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.

When you remove a bulb from a three bulb circuit, and the other two bulbs go off, then the bulbs must have been connected in __________.
