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 this symbol for?

• light bulb
• switch
• battery
• resistor

If the voltage in a circuit is doubled, what happens to the current if the resistance remains the same?

• The current will double

• The current will be halved

• The current will remain the same

• The current will decrease by 25%

What happens to the current in a circuit if the resistance is increased?

• Fluctuates

• Decreases

• Increases

• Remains the same
