Brainpop Static Electricity

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

• Current electricity involves a continuous flow of neutrons; 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 is static electricity caused by?

• A balance of power.

• A balance of positive and negative charges.

• An imbalance of positive and negative charges.

• An imbalance of protons and neutrons.

Which of these materials is an insulator?

• 
• 
• 
• 

How are electrons different from protons and neutrons?

• Protons and neutrons are negatively charged; electrons are positively charged.

• Protons and neutrons exist inside atomic nuclei; electrons orbit atomic nuclei.

• Electrons exist inside atomic nuclei; protons and neutrons orbit atomic nuclei.

• Protons and neutrons are positively charged; electrons have no charge.

What role does adhesion play in static electricity?

• It causes atomic nuclei to become unstable.

• It makes sure that atoms stay neutrally charged.

• It prevents certain materials from giving away electrons.

• It pulls electrons from one surface toward another.

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.

Lightning is a form of static electricity. What can you infer about what happens when lightning strikes the ground?

• Protons and neutrons are transferred from the clouds to the ground.

• The ground becomes negatively charged.

• Electrons are transferred from the clouds to the ground.

• An electric current is established between the clouds and the ground.
