Electricity Final Quiz

Which of the following best describes the role of electrons in creating static charge differences?

• Electrons are stationary and do not contribute to static charge.

• Electrons move from one object to another, creating a charge imbalance.

• Electrons cannot move out of the atom.

• Electrons are only involved in current electricity, not static electricity.
