Unit 3- Batteries

What makes a motor spin?

• Light bulb

• Galvanometer

• Battery

• Switch

How can the direction of the motor spin be changed?

• Changing the battery direction

• Adding more wires

• Using a different switch

• Connecting to a different circuit

What is the unit label for an electric current?

• B

• A

• M

• G

What is the relationship between the connection of batteries and the size of the electric current?

• No relationship

• Size decreases

• Size increases

• Size remains the same

How can the motor be made to spin faster?

• Adding more switches

• Using a bigger battery

• Removing the wires

• Connecting two batteries in series

Why are symbols used to represent circuits?

• To confuse students

• To complicate the topic

• To make it easier to understand connections

• To hide information

What happens when two batteries are connected in a parallel circuit?

• Motor spins slower

• Light bulb turns off

• Light bulb dims

• Same as one battery

What is the purpose of a galvanometer in an electric circuit?

• To control the motor speed

• To measure electric current

• To change the battery direction

• To connect wires

What type of circuit increases the strength of the electric current?

• Series Circuit

• Parallel Circuit

• Perpendicular Circuit

• Solo Circuit
