Static Electricity Assessment

What is static electricity?

• The flow of electric current through a wire
• The buildup of electrical charge in one place without current flow
• The movement of protons through a conductor
• The transfer of neutrons between objects

Which of the following is NOT a way objects can become charged with static electricity?

• Conduction
• Nuclear fusion
• Friction
• Polarization

In the process of conduction, what actually moves between objects?

• Protons
• Neutrons
• Electrons
• Atoms

When an object is charged by conduction, what is true about its charge compared to the charging object?

• It will have the opposite charge
• It will have the same charge
• It will have no charge
• The charge is random

What happens during static electricity charging by friction?

• Protons move between objects
• Electrons flow when objects rub together
• Neutrons are exchanged
• Atoms split apart

In the process of induction, what is true about protons?

• They move freely
• They are fixed in place
• They jump between atoms
• They disappear

What happens to electrons in an uncharged object when a negatively charged object approaches during induction?

• They are attracted
• They are destroyed
• They remain stationary
• They are repelled

What happens to electrons in an uncharged object when a positively charged object approaches during induction?

• They are repelled
• They are destroyed
• They remain stationary
• They are attracted

How is polarization different from induction?

• In polarization, electrons move to opposite sides of their atoms
• In polarization, protons move freely
• In polarization, neutrons are involved
• There is no difference

Which statement about static electricity is FALSE?

• It involves the movement of electrons
• It requires current flow
• It can occur through direct contact
• It can happen through friction
