In a parallel circuit if one light bulb goes OUT; then they ALL go out. TRUE OR FALSE?

• TRUE
• FALSE

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 has more than one path to flow through

What is a switch's function in a circuit?

• to make the current hotter or colder
• turn on and off the flow of current
• the pathway that current flows
• to add more power to the circuit

• Circuit
• Insulator 
• Resistance 
• Conductor 

A material in which electric currents are not able to move easily 

• Circuit 
• Insulator 
• Resistance 
• Conductor

When there is only one path for electrons to move through it is called a _____. When one light goes out, they all go out. 

• series circuit
• parallel circuit
