Electrical charge built up on the surface of an object is called _________________.

• static electricity
• current electricity
• lightning
• electrons

What is the major difference between static electricity and current electricity?

• Current electricity involves a continuous flow of elecrons; static electricity is a sudden transfer of protons

• Current electricity can be deadly; static electricity is almost always safe

• In current electricity, there's a single transfer of electrons; in static electricity, there's a steady flow of electrons

• Current electricity involves a flow of electrons; static electricity involves a single transfer of electrons

What happens when you touch a metal doorknob after rubbing your shoes on the carpet?

• The doorknob sends a burst of electric current into your body

• Millions of electrons go from your finger into the doorknob

• The doorknob sends millions of electrons into your finger

• Your finger becomes negatively charged

In the circuit, if you replace the paper clip with a plastic spoon, what would happen?

• The bulb wouldn't light

• The bulb is dimmer
• The bulb is brighter

• There is no change

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

• One
• Two 
• Three 
• Four

What is a Parallel circuit? 

• Has only one path 
• Has more than one path 
• Allows energy to travel through easily 
• Has only one light bulb

this circuit is .....?

• open
• parallel
• closed
• The cutest little circuit evah!

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.
