Static Electricity

What is static electricity?

• An imbalance of electric charges within or on the surface of a material or between materials

• The flow of electric charge through an electrical conductor or space

• The neutralization of a charge

• The separation of positive and negative charges in atoms

Answer explanation

ABCD

What causes static electricity?

What is the triboelectric effect?

• The exchange of electrons or ions between materials on contact or when they slide against each other

• The neutralization of a charge

• The separation of positive and negative charges in atoms

• The flow of electric charge through an electrical conductor or space
