• Open

What is the power source in this circuit?

• Bulb

• Switch

• Wire

• Battery

How many paths does a series circuit have?

• 4

• 3

• 2

• 1

The voltage stays the same in a series circuit.

• True

• False

What is a circuit with several paths for electricity to flow?

• conductor

• series circuit

• parallel circuit

• open circuit

This circuit has a battery, buzzer, and switch.
When the switch is closed the buzzer will sound because -

• the switch gives energy to the battery
• the buzzer is made of special plastic
• the wires are cooled by the surrounding air
• electricity can flow in a complete path
